Bro, you give the best info, and to the point. I dig the channel. Keep it going. BTW what is your wheel set up?

This guys a different breed, I watch these videos even tho I have a n54

Best Video! Personally I run Stage0+ (Soon Stage1) already got 300cell DP. I just can recommend the DP and xHP even for stock cars. It makes it much more responsive and shifting not only in Sport/Sport+ nicer but WAAAAY smoother in Comfort. Just get xHP.. Also reminder, you have to go ~60miles in comfort, no kickdown, no manual shifting, no sport mode after flashing xhp to let the transmission get new gear adoption values etc.

Fantastic info man

Right now I'm running a decend 440 hp stage 2 with about 635 NM of torque and it suits perfect for a M240i. Everything above is like just burning Tires for no reason unless you really wanna compete in Dragraces. Guys be safe out there and choose a good tire if you want to have performance for your HPs.

Will be buying my 4th BMW soon, God Willing. I have been Looking for something like this FOREVER !!!!!!!!!!! Your information flow matching the logical evolution of this engine is the absolute BEST I have ever heard and believe me I have 2 Doctorates in You Tube. Thanks soo much for this !!!!

This is pure gold Kevin! Thank you sir 🙏🏻

Keep it coming bud🚀

Fck, these engines really sound like they're bulletproof for some minor mods. Never thought I'd see a turbo BMW be able to handle 500whp on stock internals. Crazy.

Getting a Stage 1 Tuning next week. It will be 430hp 580nm

Great video! Going to go stage 1 on my m140i soon knowing that the engine is capable of much higher

Thanks for being you and sharing your experience and knowledge.

my m240i pushes a bit over 600hp on 98 with a Hybried Turbo a Dorch Stage 2 HPPF and a Catet Downpipe and im now going on E20-E30 and look what the Car is going to make

Thanks a lot for such informative video! Gonna boost my F32 to stage 2 soon!

Great Information brother, give thanks 🙏! I just bought a 2019 540i , thinking about stage one for starter

M240i owner, and honestly this car is so fast stock I can't imagine finding it necessary to go past stage 2 at most for everyday street use!

I just saw your TikTok on my fyp and now your on my recommended videos 😂

I bought a used 540i with 60,000 miles and I’m contemplating just doing stage 1 . Ideally I’d like to drive this car a bit past 100k miles and I’m sure it can do it just fine.

Loved this video. so much knowledge THANK YOU

Got my m240i with the b58 2 weeks ago with only 50k miles on it and just loaded it with stage 1 with intakes and DP along with xHP stage 1 and WOW, it literally feels like my chest is being pushed through the seat when you put your foot down at 40 mph

I’m new to a boosted car and bmw. i just got a 2016 340i and I’ve been watching most of your videos. Is there a specific reason why we don’t need spark plugs? Your helping me learn so much about these cars btw 💪🏾!

I have a BMW x4 M and I got a Downpipe and ecu tune and e25 and i got like 250 extra hp the mods are worth the cash

Excellent guide. No need for some knob driving around saying check out my MHD generic settings. 👍🏽

You should do one on What are stock Drive train limits like axle ,and Diff, driveshaft etc

What about downpipe on bm3 stage 1? Worried about putting the stage 2 with manual clutch. .🤔🤔🤔 Keep going with this b58 videos.

Great video broski! 🤘😎

Thank you for this vid 🙌🏾🙌🏾

Those power figures you post at end is that for rwd or awd applications. Big difference. If a stage 1 rwd is 380-400whp the awd version is at least 20hp less

New subb. I love the vid, thank you for all the info. Was considering changing out my charge pipe and down pipe on my 340 6speed before going stage 1. Was told the B58 charge pipes are stronger than previous gens so don’t really need to do it. Didn’t really plan on going past stage 1 but if i’m already swapping out down pipe and that’s the only mod necessary to go to stage 2 i mite as well. My question is, if i just swap my down pipe for a high flow catted one and go stage 2 i shouldn’t run into any problems rite? Also, what platform would you recommend? Been looking at MHD, and Bootmod3.

Amazing vid once again! 👍

Great way to save the intake manifold is to get an oil breather cap. Massively reduces the pressure

I love you

I’m assuming these stages are different than a JB4 stage tune. Is it worth upgrading to an MHD over a JB4 if you have a catless down pipe/intake/charge pipes?

Thanks for posting 👍

Still got 3 years and unlimited miles on my M40i’s warranty. After June of 2026, I may start modding.

Just picked up an Ineos Grenadier w/ B58. I am thinking the stage 1 is an easy upgrade? True?

Damm all i want is to be on stage 2 and e85 😂

pops and bangs from the downpipe are great

Do you have a video on maintenance schedule for tuned cars?

Hey man! Thanks for all the videos and forum discussions! Loving it. I have made my g30 b58 gen1 up until this point to stage2+, but now stuggling a bit with settings for MHD tune - particularly should I tick the box for TCU TQ limiter removal or not? In theory mhd says st2+ is up to 520hp and 720nm, so even in a worst case scenario i would imagine my engine will be exceeding 550nm limit of the torque (apparently stock is around 450nm so with st2+ should easily go beyond 550nm, shouldn’t it?). Thanks for help in advance and again, loving my car now and your videos helped a lot!

Solid video. Really glad i came across. I have a 2019 540i xdrive BMS intake VRSF catless downpipe VRSF charge pipe JB4 tuner and i usually sit on map 2 or map 3. What “stage” am i? Have not done dyno yet

Hey, I also have a manual but I have some questions. At what kind of power did you decide you needed to upgrade the clutch and did you do the flywheel as well? I feel like 2-2+ would already be in the range of causing slipping sooner rather than later but maybe that wasn't the case for you?

What’s up guys, I have plans for over 500hp. Although, I’m at a toss up. Should I upgrade turbo first then install meth kit? Or meth kit first then turbo?

Hello! What about the Air Intake? You have yours replaced, as we can see.

@kern417 Darnit! Just found out your in Cincy! I was there the other day getting a carbahn tune at jake Sweeney bmw… so far I have AWE exhaust with AA downpipe. I got impatient and did the tune with 10 months of factory warranty left, but I also added the Carbahn matching warranty. It’s not a huge bump, but enough to notice! In your opinion this should be a fairly safe and mild tune?? The plan is to switch to Ecutek or BM3 next year once warranty is done. Awesome content btw!

You’ve given me great advice before so.....but I have done these calculations in my head over and over... Here’s my logic- 1. Stock 340i ( I have Xdrive btw ) from all I read makes 350-360 hp stock at the crank. The whole underrating thing. So I took 360 hp x .20 ( my awd ) and came up with around 290 hp TO the wheels stock. 2. I have BM3 stage 1 and most seem to say, including PTF that stage 1 is %20 increase in HP. So I took 360 hp x .20 which then is a hair over 430 hp TO the crank. Reverse that equation and I came up with around 345 hp TO the wheels, for in my case ALL 4 wheels. Keep in mind NO other mods other than tune 3. BM3 stage 2 , whose power seems to be derived mostly from the freer flowing downpipe supposedly makes an additional %6 over stage 1. So with that in mind you would end up with around 450-460 hp TO the crank. In my case in AWD x .20 then a total net of around 365-370 hp to ALL wheels. But the caveat here for me is the other day I ran a roll race from 50 against a supposed “414 awhp” later model WRX and even with me starting in 4th gear ( I have auto trans ) instead of 3rd gear like of should of, he only maintained a 1-2 car length lead on me up to about 100mph......he seemed a bit surprised when I told I was running only 340’ish to the wheels despite also his car being almost 400 lbs lighter than mine. So either my car DOES have more than 340 to wheels OR his car was NOT 414 to the wheels! I guess only way is to dyno. I will say though that I have gotten a 4.1 zero to sixty using my dragy and that was without LC only brake boost up to 1300 or so......and again with only stage 1 and NO other mods whatsoever. I’m glad you take the time to post stuff like this. It gives me other angles.

I just took my x3 m40i to a hub dyno it was making 455 to the wheel consistently

Do I need an upgraded fuel pump either 2019 440i? Cuz I know its a gen 2 pls let me know

Hey, do you recommend upgrade draft shafts once big turbo? Will be doing diggs with the car

MHD also requires a GPF delete for stage 2 but I never see anyone do it. Any thoughts?

Perfect video!!!

In the video, when you're talking about up-grading internals and cracking intake manifolds are you referring to BHP or WHP??

On point with everything,very nice video,congrats. On an M340 with pure 800, downpipe, change pipe,hpfp, and a Trans tune , on 93, it is possible to run more than 600whp? And it’s a daily what should i upgrade more?

What do you think about the M Performance Power and Sound kit? From bmw?

Do you have any experience with Hybrids ? I have a bmw G05 45e. Just got down pipes installed 300 cell, and looking at ECU tune and custom exhaust with GPF delete. Tuner states around 500-520hp for stage 1. Should be no issues with engine and transmission. Any comments here from your side ?

Is the stage 1 safe for stock clutch and gearbox, for manual transmission?

Thank you

anyone else running stage 2+ and issues so far? i’m 4k miles in and was wondering about long term reliability

That filter is killing you.

Currently running a custom stage 2 tune, 455 hp and 618 Nm on my M140 Xdrive. Recently had the TU pump fitted as precaution. Is it worth re-tuning to stage 2+? Will the power gains be noticable from stage 2 to 2+ ?

does stage 2 93 OTS with a catted downpipe for daily require clutch upgrade?

Can I get those tune from a bootmod3?...and can I upgrade down pipe...fuel pump if mt car is 2022...and I don't wanna flash computer yet..."warranty"

Is the 550i clutch hold the torque from the stock turbo on stage 2+ and the GC+ on pump only ? Probably around 550whp or less

I love it nice and simple bro I have a m140i sage 2 and my next step is 640bhp sage 3 pureturbo and I am finking of my clanch that you say 335is but from wich your my car is 2017 so don't know

great break down. i know audi / vw stages like the back of my hand but now that i want to switch to the bimmer life this was invaluable for the b58 So the charge pipes are solid in the b58? i remember that being a big problem in the n55

I have a carbon tune, vsrf catless dp, intake and dinan exhaust. Only able to run 91 octane. Would I get power gains just from installing a water injection kit? Is a water injection kit as good as doing the HPFP upgrade?

What stage 1 tune do you recommend

I have a B58, 2018, 540i BMW and I’m looking for recommendation who does the best tunes? and a tune that’s compatible for down pipes as well because there’s a lot of people that do tunes, but don’t tune for downpipe’s

Hi! Can i put a better intake with the m performance kit? Does it work ? Or I have to change the exhaust system or downpipe? I Mean can i make stage 2 with the m performance exhaust?

Do you have a preference between BM3 or MHD? I like the features each one has but I want to make the most reliable power I can using one of their OTS tunes, it does seem like bm3 isn’t as good with timing opposed to MHD. I can’t really find any solid Dyno comparisons between the two (stage 2 dyno numbers) but I plan on going Stage 2 for sure and possibly stage 2+ with HPFP to possibly run an e30 mix every so often.

Hey looking to get a TU PUMP and help with where you buy one online would appreciated

I heard it’s recommended to run ngk 1 step cold plugs is that true?

So please correct me if I'm wrong but... Aren't the ECU's in B58's built after 06/2020 locked and a bench unlock for the Dme is not yet possible? This leaves some of us with either Jb4 or racechip as an option? Or do you know something I don't?

I had a quick question regarding my manual 2018 340i. I got stage 2 E30 from BM3 running right now. I had an issue where I would go WOT and around 4k rpm or so the car would make loud pops and cut back on power. It wasn’t consistent. Sometimes it would happen and sometimes it didn’t. The RPM it would happen at would vary at times too but usually around 4k. At first I thought it was my clutch was slipping. So I had it replaced because it needed to be replaced anyways but that didn’t solve the issue. You got an idea of what that may be? I’m hoping it’s just me not having a good e30 mixture.

So does the "tune" only effect the sport mode? IE after you tune your car will running in the eco mode be the same if you are not looking to push it?

Still loving the content on this channel and please keep it up! I just installed MHD today on my 18' 340i RWD. I fitted the FTP chargepipe and intake pipe with a drop in BMC filter, catless downpipe and the TU pump. I went with 91 Oct stage 2 and did a dyno run. The results were a bit underwhelming 269wkw (361whp) and 587nm of torque. Do you think this is normal and could be a stingy dyno? Also the tuner that helped install my hardware said he does not recommend even loaded the stage 2+ even though I have the pump because in South Africa our fuel quality is poor. Would love to hear any thoughts on this.

Hi, would you still need Xhp with stage 2+ please?

What's your best recommended setup for a reliable ACN 91 octane flash and power ...have really terrible petrol quality here and I am contemplating a MPPSK for the sound and extra performance OR a stage 1 ACN OTS map with a catted downpipe

hi, great info thanks, i have m240i manual with mhd stage 1 tune and a de cat downpipe , dont like the smell now so want to put std downpipe back in, does that affect the tune as stage one is generally ok with stock everything ?

I have a Vargas VTT GC on the way as well as a VRSF high flow catted DP. Would I be able to expect around 450 WHP from a OTS stage 2 93oct tune with this setup? I plan on getting a Dorch stage 1 and a custom tune eventually but just curious how these current mods will handle until then.

How reliable are these mods at like 500 hp?

for mhd stage 2 do you think its worth getting xhp software or tq isnt high enough for it to make a diff? thanks

Hey Kevin. If I want to add an aftermarket CAI on stage 1/2 for better noise not performance. Would that be detrimental or great compared to the OEM intake?

Just got my 340i m sport about a month ago, what tuning company do you recommend? I’ve heard of mhd and bm3 but can’t decide on the two.

Sick video. I highly recommend an LSD to actually put that power down. Currently a stage 2 b58 with LSD + Trans tune as my next upgrade, then saving up for HPFP/turbo. I heard upgrading the heat exchanger is necessary in hot countries. Any idea how complex/expensive it is to strengthen the transmission?

hey boss!! I have a 2020 m240i x drives completely stock thats about to come off warranty. Keep it as is and trade it in or enjoy it for a year or two with a tune? thx

Hey man I recently did a downpipe and stage 2 bm3. Got codes for clutch slipping “badly” and intake VANOS. I can’t pull hard at all without dropping revs and going wonky. What would suggest? Just warranty the clutch and do the vanos and hope it works ? Manual transmission

I have an 2017 M240i xdrive, im stage 1 no upgrades yet, I have DP and chargepipe that i’m about to get installed aswell as a dinan intake. Will that set me up for stage 2 and still be just as reliable as it is now? or should I get an intercooler as well? my tuner says I should but I hear many different opinions

How much does the B58 version matter here? Does the B30M0 catch up to the B30O1 along this upgrade path or live with a permanent handicap given the same mods?

The new supra is b58 right? Hope u make a vid about the new supra and what mods to add on

f22 here and that fuckin turbo is seX 🤤🤤🤤🦈🤤

I'm running stage 2/sport cat/LSD/Xhp flashed: Can I upgrade my fuel pump B58tu without go to Stage 2+?

Currently running MHD stage 2 93 with catless downpipe and xHP stage 3. If I move to MHD stage 2+ with b58tu hpfp but stay on 93 without ethanol would it be worth it? Will the stage 2+ map give me more hp without running ethanol?

can I run an e85 and 93 mix with the stock fuel lines on a BMW X5 40i drive 2019

What of these tunes retains the stock reliability and longevity?

For stage 2, uprade charge pipe is needed? Some people is blowing it

Is the charge pipe not really necessary for stage 2? The stock is made from plastic

im going to get a pure800 turbo for my b58 soon, should i upgrade the intake manifold? im going to have csf heat exchanger catless dp dorch stage 2 hpfp all installed with the turbo

If just going for a stage 1 upgrade. I was considering a BM3 stage 1 map. Catless downpipe and OPF Delete. I know the downpipe is not a requirement however choosing it for better breathability and power delivery . Thoughts ?
