14-16 Lexus IS250 RR-Racing Tune Install (AMAZING RESULTS)! 

Lol I had to shout out a legend 🙏🏽

Glad I can help

Fr

Came across his page looking for ideas and bam, found your comment. I too own the same car as you. Needa pick your brain. What all have you done to your car?

@@martinorozco1692 invidia mid pipe and invidia exhaist, Fsport air intake system purchased from Lexus dealer , lowering springs , Megan racing strut tower bar, crossed drilled and slotted rotors , pedal commander throttle booster , front splitter and new rear diffuser . And of course the RR Tune. Just ordered the PPE headers with ceramic coating from RR. Takes like 4-5 weeks for them to get them and then will have them installed at RR .

@@Jamesfitnessfreak thanks man!! Doing my research as we speak! Any bolt pjs you recommend?

@@Jamesfitnessfreak how many horses are you pushing do you know ?

@@Ivansoasiann Stock is250 is rated at 206 , the tune from RR is rated at 27, then I have midpipe, exhaust, air intake and Ppe headers which were tuned again , nonspecific numbers but I’m guessing somewhere in the 275 area .

@Jesse Navarro 17-19

Do you recommend it? Does it affect the reliability of the engine?

Thanks man Glad to hear 🙌🏽

Hell yeah definitely man.. I’m hoping all this covid shit calms down so we can hit some of these car meets

Chris Kheluram word bro u got ig ? I’ll follow you I’m @flubackbaby

My bro! Thanks dude I will def do a update video on the tune

Thanks bro 🙏🏽

Come on dude I’m not trying to be the reason you spend money 🤣😂, but thanks homie

Glad to here the instructions are very well detailed.. I mean they are a couple things I would add like all the warnings that come up when writing the file on the ecu etc. which definitely scared the shit out of me. But other than that its simple but if anyone is like me I like to visually see things done but I’m glad to hear your car is running good makes me feel a lot more confident about the tune

@@ChrisKheluram yeah I agreed. My car is been running fine. And so far is the best mod that I did to my car.

@@kyledu0766 How has your car been so far? I already have a Takeda intake and Ark exhsust installed. Planning on putting headers on my IS350 (16). Do I need to tune it?

Thanks bro.. I mean I would definitely consider it eventually man

Thank you for the feedback.. I didn’t know different dealership Lexus offer different prices lol basically I got robbed 😂😂 nothing new.. as for lock up in auto.. what do you mean exactly ? I’m just curious

@@ChrisKheluram if you accelerate all the way to 7200rpm, it won't shift to the next gear. I found that out and ask Simon about it. Some models and year does that on automatic. Something they didn't disclose on their site.

And I got a free car wash when they was done😂😂😂 sorry you got robbed lol

I see.. I’ll try it out.. reason I want to know is I’ll be doing a update video on the tune itself maybe today or next week and I would like to use my car as a test.. let me know if you want me to try test other things out.. again I still got to be aware of the law lol

@@ChrisKheluram yeah bro. People rely on you for facts and truth. Honestly, I can't have anyone drive my car unless I tell them what it does or else they might blow my engine. I have a 2014 is250 non f sport. On automatic, sometimes it like to shift from first to third skipping second. Don't get me wrong, I like it but I'm not sure how really safe and reliable it is.

😂😂😂 I got you and to answer your question it is actually better then a throttle controller because it increases HP, shift points and rpm limiter.. the throttle controller does not increase HP BUT! It really makes the throttle response so much more better.. so if you’re on a tight budget go with the throttle controller or if you just get the tune from the beginning

That would work too.. if you get both it works well with each other so your can’t really go wrong with either or

Absolutely! Second that.

I agreed 110%

How much yo increase u seeing

That apexi thrttle controller gives you the check engine light and messes with throttle

@@andyy7078 zero issues here

Honestly if you really love this Lexus chassis is250 is great when it comes to price budget. It does lack performance and there really isn’t a good way to add HP unless you super charge it. Which makes no sense to me personally. IS250 has the looks don’t get me wrong but that’s all it is. Reliability engine wise, has been great to me, water pump is probably the only thing I’ve changed since I owned the car. If you do get a IS250 make sure it’s 2015+ since 2014 model will have majority of that radio/amp issue like I have right now that makes me want to get rid of the damn car. a air oil separator would be a must because it is direct injected not port like the IS350 is. And I would also get a Throttle controller to eliminate the throttle delay for a better drive. Tune is over rated for a 250 unless you buy a IS300 which is no different than a 350 it’s just detuned from factory. Which the RR tune will bring some of that HP back with supporting mods from my understanding, don’t quote me on that lol. If I had to do it again I’ll save up and get the 2015+ 350. But not everyone can and at the time I bought mine I still couldn’t afford to even have a IS250. My thing is now buy once, cry once.

@@ChrisKheluram Hey Chris. First of all, thank you so much for taking the time and give me a very thorough, informative reply. I appreciate that. Yep, unfortunately, in my country, we don't have the IS350, never had them, unless 100 units of the 2008 version. 😢 So, If I really want an IS, I gotta go with the 250 or go for another car. There's one here, in great shape, 2014, I talked to the owner a lot, he takes very good care of it and I test drove it. The only reason he's selling is because he wanted to buy a Subary WRX or STI, which he just did, bought a WRX. So, although I think the power should be enough for me, specially for daily driving, I'm still not sure and I can't test drive it anymore and it's in another city. So, I'm really not sure weather I should buy it. LoL But it really seems to be a very nice car. Would you recommend it? 😃 Thanks

In that case, yeah I would.. tbh it has the reliability and looks and if you really like it go for it. Please keep in mind the radio does have an issue so keep an eye out for water in the trunk area as well as the radio itself

@@ChrisKheluram Thank you, Chris, I appreciate it

Following. 08 350 here

Great man the tune is definitely a good buy 👌🏽

It wasn’t that much but it is def fun to drive

They actually could've gotten this engine to about 250hp.

When I was putting a video together I tried to contact one person to use their video for a comparison and when I uploaded it it got copyrighted lol so unfortunately I won’t be able to get you 0-60 before but I can try do a after video now. Once I get the chance too

Me personally I love the lip kits from NIA auto design very uniformed and clean. I would talk to RRRACING to see if there’s anything in development for a tune. As for exhaust everyone seems to go with the invidia RC350 ones these days ( I guess it’s Jason Nguyen and myself fault for promoting it so much ) but 🤷🏽‍♂️ all you have to do is cut a small section off your diffuser. But you might not even have to with the 2020 model diffuser (again I really don’t know much on 2020 models and the differents) that would be up to you. And if you want a louder tone change out the midpipe if you have kids probably not a good idea. maybe a spoiler and some coil overs / air suspension. You can even run lowering springs if you wanted. Don’t take much to make these cars look fire dude. Thanks for the comment and make sure to sub 🤟🏽

@@ChrisKheluram thanks man, appreciate it!

Unfortunately you are right. There isn’t A LOT of aftermarket parts out for Lexus 2is or 3is but they are enough to make these cars look and feel much more fun to drive 🔥🔥, these arent a 240sx or a EK hatch; were you have a whole spectrum of parts to choose from. If you’re looking for a car with more of a aftermarket platform performance wise this isn’t the car you want. If you want a nice decently powered is350 cause you genuinely love the look of the car then go for it. Again, it’s your choice at the end out the day but one thing is to always make sure you do every bit of research before buying and committing to a car/build and ask yourself where do I want to go with this build and is it in my budget.

@@ChrisKheluram thanks bro. When it comes to buying a car I'm usually a looks and sound type of guy and then I factor in hp gain potential and the last 2 cars I had including my current one don't come with much hp from factory I wanted to get the 2is350 but I love the look and sound of the is350 and not to mention lexus reliability so i might still consider it as a car I'd choose off of those 3 things alone but I'll keep track of everything until then.

They are truly reliable cars but they heavy AF lol so carbon fiber bits will be a must 😂

Working on it right now 🙌🏽

It definitely does work and it feel a lot better with it but it’s definitely not needed the tune is more than enough

Chris Kheluram ooo sounds good 👌

✊🏽✊🏽✊🏽 it’s a awesome tune might have to learn to “shift” cause you only really feel the power in “M mode” from my experience

Looking forward to an update as well, if I had to guess I would assume everything would take up to 30 minutes to an hour max to install if you have troubles, but everything is so self explanatory after Chris explained everything. You really shouldn’t have any.

This can be done in a day depending on how long It takes rracing to send you back a updated tune for your car. All you have to do is send rr racing your tune once then get to you you take that tune and instal it on your IS

Thanks dude. It really is self explanatory rr racing does a great job explaining everything on their step by step instructions

For a is300 you gain the most HP out of town he 250 and the 350 which is insane, I highly recommend this tune. I will be doing a update video within the month

You can do any IS but it only is one per car

Couple days for me because I didn’t have the PCM update from Lexus RRRACING needed so once that was done the tune took like 15-20 mins to install because I took so long to read instructions so I don’t mess up lol

Thinking about getting it for my slow IS

Yeah It did lol, I was scared to too but it did go away the car was running through its system and also when I started the car it shut off right away. But then I started it right back up and it was great after that. I push the crap out of this car in the past 2days and I’ve have no issues

I’ll also being do a update video very soon

Chris Kheluram It shut down after the first start with the tune ??

Yeah the Lexus ecu aren’t like older ECUs on they need to relearn the changes so the shutdown is like a reset

When I did mine i was like oh shit my car is dead, because for some reason on the first start up after the tune my car litteraly stalled out for no reason. As far as longevity, had it for like 2000 miles on my car (1500 of which were long distance from MI to TX and ive been very happy with it).

That’s actually a really smart idea and it’s recommended but I don’t have a driveway nor do I have a garage so 🤷🏽‍♂️ got to work with what I got lol

Tsudo mid and invidia axle back ✊🏽

@@ChrisKheluram That’s sick I was thinking of going full Tsudo exhaust system since it’s very docile at low RPMs and it sounds tame but loud at high is that right?

You can tune before installing the intake and downpipe but if I was you I would install everything one shot. Although Lexus ECU’s are self learning it’s just better off to get everything one shot. And you need to find out if RRracing makes a tune for is200t I’m unsure if they do. If not there are other tunes out there for it I believe

@@ChrisKheluram Okay, Thanks.

Yeah i did and I love it dude.. that ecm thing sucks but too have a tune it’s well worth it

I completely agree I’ve had cars faster then my 250 and I loved it, I’ve sat in peoples cars way faster then mine; in complete jealousy lol. But Tbh I was college grad with a totaled is300 and barely any money and I truthfully made a bad decision buying this car. But in a way, I look at it as the 250 is a challenge on its own to make it a fun car to drive. I kinda accepted that challenge by trying new things to it to kinda convince people that maybe own a 250 and can’t upgrade or can’t afford a 350 or 300 but still loves the look of the car, that it can something enjoyable without some people saying “should’ve just bought a 350” (not you just in general) lol. Reason why I started RU-vid in the first place. I will eventually upgrade but for right now I’m going treat this car as if it was a LFA 🤟🏽

As a current is250 owner to a former one ... what did you upgrade to ? 👀

Lmao I never realized, I thought something was wrong with my headphones for a second

Me personally, I would keep the stock air box.. I know it doesn’t look appealing or sound nice but it’s super efficient. You want something that will ingest cooler air rather than hot engine air. Being that the afe intake filter is not in an enclosed box the performance might suffer a little. I’m no expert lol but I think a intake tube would be a better choice. But if you really like the AFE over just the tube, the it’s up to you bro, intakes in general don’t really make hp unless you have it directly behind your front bumper air vent; which you don’t want to do if you daily you car lol.

@@ChrisKheluram word, ight bet. I appreciate you bro fr !

Tsudo midpipe and invidia exhaust there’s a “all mods” video on my channel with all the links provided 👌🏽

This overwrite the ecu but it can be put back to normal if you needed it to be.

I believe this tune was tested on a manual is250 from rr racing so I would definitely think so

Thanks man and I don’t know exactly but there’s a company in NY that specializes in infiniti called @realautodynamics on Instagram. Hit them up and speak to Alex they are cool guys

Yeah ofc this will not effect anything other than your hp and torque peak. It will not effect your eco and normal driving mode nor will it affect your AVS suspension from what I know. However The tune will perform best when set to sport+ mode

@@ChrisKheluram thanks for the reply.

To be honest with you.. I don’t ever drive in “D” I’m usually In “M” mode which shifting on you’re own. I come from drive manual I absolutely can’t do the automatic. But the 7200 rpm range doesn’t apply to the automatic mode

Not so much of a issues, more of a side effect. With hard driving stock the toque converter locks when shifting for more immediate soled shifts than any old automatic that dose not do that. But it only locks up until 6800RPM, so any shift done at a higher RPM like that of the RR racing tune could unlock, would not lock the torque converter and hence take longer to shift. Can't speak personally as my RR racing tune has the stock rev limiter in place, but apparently the slower shifting is made up for by staying in the power band longer.

@@tv321123 did you ask them to keep it at the stock limiter? I didn't realize I had a choice because if I knew that, I would have kept it at the stock limiter too

@@tomotee-o941 Yes I specifically asked them for the stock limiter from the get go...I just wanted to go from a stock AWD 300 tune to a stock 350 tune. Although now I'm looking at getting the full RR racing map with the extra power and increased limiter.

@@tv321123 I wish I knew that from the beginning. Their site didn't suggest that I had the option to keep stock limiter. I think I'm going to inquire about a different tune from Simon.

It’s still has some function but you do feel it as much as more since you’re getting constant throttle response throughout all speeds of the trans. But yeah you get a nice response once you step on the accelerator after 4th you don’t really feel it

Chris Kheluram thanks for the response man and I can’t wait to try it out, will definitely check out more mods you’ve done...

Yeah man anytime 🤟🏽

Thanks bro

Never know man, I just might

No headers 😢

Right?!!!

Bet y'all both drive 250's

.. what gave it away? Couldn’t have been the title there bud

@@ChrisKheluram the two smiley faces with heart eyes That gave it away Yeah

😂😂 Word of advice, don’t be jealous

I do have the intake but tbh man in the beginning you do feel the throttle response to be a lot better but I’m so used to it now I don’t feel a difference anymore. The apexi throttle controller with the tune does take it to another level for sure

Sounds crazy especially in tunnels

We don’t have MARK X in the states although we have the same engines and OBD2 (I think) ports the ecus are different, so I would advise you to contact RRRACING since they need to send you a tune file anyway

Unfortunately they don’t but fortunately they sell a lot of other power modules for a is200t

Let me know if you pull the trigger wanting to do this soon

🙏🏽🙏🏽🙏🏽

The only way you’ll know is when you get the tune controller RRRACING sends you you’ll have to extract file from your ecu and send it to RRracing via email. They will open the file and tell you you need a pcm update or not

Unfortunately I don’t think they’re are tunes out for a es300h man

They really don’t believe in the whole flame thing lol since stock motor doesn’t really have the horsepower to do that. In order for any tuner to do that you will need to retard timing (something like that) and that can cause potential issues long term. you can ask them if they can do that for you but idk. If you do want that there’s people out there that works for a company called mforce tuning but again idk how to get in contact with them. Also I don’t advise getting any type of flame map on stock motor unless you’re pushing 500-600 hp with a fully built motor with turbo, 1000cc+ injectors and beefy fuel pump

@@ChrisKheluram yo do you think this work for my 2009 version

RRRACING has tunes amongst other performance parts for ISF, RC, GS, etc you would have to check the website pertaining to your car

Unfortunately it is based my ecu ID therefore I can’t resell. It can be sold but If I do resell it I will not be able to reset my ecu back to stock if If I ever need too.

😂 sorry to burst your bubble but I don’t live on a drag strip. you can definitely buy the tune and try it for yourself.

@@ChrisKheluram im sure their is an old road somewhere😂 ever considered buying a draggy for like 60 bucks records all 0-60 0-80 0-100 quater mile times and everything just buy having it in your car

🙏🏽🙏🏽🙏🏽

Did lexus update your pcm software or yours was always up to date?

Chris Kheluram yes my software is up to date but I’m heading up to rr racing tomorrow

@@scotts1440 So what happened? Year and model? Thanks

@@ruthnoya8424 had sent me the wrong file because Simon had made a mistake. Me and another person had the same first name and was messaging him the same time so he got confused

@@scotts1440 How has the tune been? Do you feel it was worth the cost or would've been better spent towards headers/midpipes or and is-f steering ecu or ?

Stock is about 7 secs and with the tune I have no idea but it’s not much faster on a is250.. I would really love to get a dragy device to measure the actual time

I do have exhaust, intake, no headers.. your RC350 has a way bigger engine displacement then my 2.5. You should definitely feel some results as for number I have no idea never dyno my car bro

@@ChrisKheluram I'm excited bro ,I ordered mine last night . Can't wait to see the difference it makes , the sprint boost throttle control i have is insane ! I subscribed ,keep making those videos bro .

I’m sure you can fine tune this tune and dude I prefer old 90s tech and engines anyway.. And yeah you do need standloads just to squeeze a shit ton of power but it’s worth it and does engines sound amazing! Stock

nvm should’ve watched the whole video before commenting😂😂

They have one for the Gs350

Honestly I used my stock 2014 diffuser and cut it to fit the exhaust

@@ChrisKheluram do you just have the axel back or also mid pipe?

Tsudo Midpipe and invidia axles back

That’s definitely understandable as for the pcm update at the dealer I don’t think it’s required on a ISF you would have to check with RRRACING. As for a tuner, RRracing sets you the tuned file after they have received your ECU ID once that’s done you take that file and store it onto your device and then onto the car. No tuner required unless you’re trying to get fined to squeeze more out of it. That would also be another question for RRracing. All in all you do have a ISF dude and that alone gets pricey with parts trust me my brother has one lol and I don’t spend not nearly as much as he does on his set up lol

And he didn’t go to the dealer nor had a tuner he just bought the tune but check with them bro I’m sure it will all work out

@@ChrisKheluram yeah I was going to get the RR racing complete package the headers the tuner and the cold air intake with the larger mass air opening and heat shield that right there is about 2,500 then labor all together well over 3000 so my plan is just to gut my cats secondary I already have a muffler delete true dual exhaust with x pipe K&N air filter with topspeed carbon fiber intake tube with the tune I think I'll get the best out of it I probably would consider getting headers for the car but I don't want to worry about getting a smog in a year or so later

I believe the only reason you would need to update your ECU at the dealer is if you don’t live in the US. I read someone talking about it and the non-us cars have a slightly different firmware. I believe this applies to the 2IS. The 3IS may need to update.

@@IndyIS350 okay good to know because I was worried about that

Thanks man

You can just get the tune without performance parts.. but in order to get the most out of a tune performance parts will eventually be needed 👍🏽

@@ChrisKheluram to make the tune work do you half to email them the software or can you just plug the tuner into the car and select certain settings. I ordered the RR racing tuner for my gs350 and I only plan on removing the speed limiter

@stephen rand I’m pretty sure you have to email them to send you the tune file that they made specifically as for messing with the settings on the tuner I don’t believe you can do that. The tuner is basically like a file import exporter of files. It’s not like a apexi FC or a COBB

@@ChrisKheluram ah ok that makes sense I’ve heard that you can email them certain specifics you want done on the tune is that true? If so you think if I email them that I only want the speed limiter removed and nothing else they’d just put that tune in it?

@stephen rand yeah I heard the same, but it all depends on RR RACING and what they say they might just tell you just install the tune they provide lol but give it a shot

Definitely not, i drive my car all day long back and forth to work, run errands etc. basically my car doesn’t catch a break and I haven’t have one problem yet. Which is one of the reasons RRRACING doesn’t offer a pop and bang tune

250 toyotas in my country see 314 hp n live lol

Thanks man, it’s a tsudo midpipe with invidia rc350 axle back

Did you notice any hp gains or lose from the tsudo midpipe versus the stock one? (Do cats add hp/ torque)

For ISF I’m not sure what file they are supposed to give but I do know if you have their Intake set up with PPE headers and a full exhaust it really makes a difference especially with the Intake due to the increased diameter of the maf housing something like that. I’m not to sure about ISF but my brother has one with the tune and the it moves but I’m not driving it every day so I’m not used to going fast lol

@@ChrisKheluram right now I just have topspeed intake elbow with K&N air filter drop-in filter so maybe yes I need to upgrade to the bigger mass air opening I pretty much have a free-flowing exhaust no secondary cats only x pipe all the way back true dual exhaust I removed everything

The isf gets one file. If you have tuned intake they send another revised file. @nathan Lopez what's your KCLV? I have the tune on my isf and I notice a difference..

@@colby3333 what is kclv??

For a 250 not much according to RR RACINGS DYNO sheet it’s like 6+ torque As for 300/350 it’s a good amount

Tunes are always better then throttle controllers

One day I just might 🤷🏽‍♂️

Lmao hell no.. but it’s a lot easier passing Nissan alitmas and Toyota Camry’s
