Kia Stinger Lap3 vs JB4 

For the difference in price I'm going to stick with my JB4

As someone who owns a JB4 I can confirm that 4.2s are the most consistent runs in 0-60. I have 25lbs wheels on 265s PS4S with SSR downpipes and a Muffler delete, all my runs are done on 91 octane on a GT RWD. However that 4.2s number means almost nothing to me as I've beat plenty of cars off the dig that claim 0-60 in under 4s. I rarely do dig races however, most my encounters are roll races.

Wow, thank you, i live in Montreal and i just bouught my 2020 Gt2 Awd, and i wasn sure with chip tune to choose now i know i will remain with my first choice. JB4 for the run. THANKS A. LOT FOR THIS VIDEO! All hail to Stinger Nation.

Personally I started out with the jb4 and then moved on to the first version of the lap3. Jb4 seemed better for launch control, but the lap3 imo was much better a roll racing. Either way best comparison I've seen, great job man.

Where them likes at! Let's get it for Stingers!

I’m running a Custom Map6 on my Stinger and it’s ridiculously fast. Map 1 and Map 2 are decent, but there is a lot more potential with E30 and improved Octane.

Enjoyed the video guys! Thanks for taking the time to put this together. I'd also like to see a 1/4 mile comparison and might as well add the Racechip GTS to the competition!

Great video. Seems like you've got some really great friends from all of your vids. Happy for you my guy!

Awesome video guys. I was considering the lap3 but decided to go with jb4 just because of the price difference. I agree completely because I was hands down going to buy the lap3 but then I said to myself there probably wouldn't be much of a difference between them. I am however a veloster N owner sadly I didn't buy a stinger almost did but wanted to do more track days than drag racing. However I don't believe you guys were unfair in your comparison. Great job loved the video.

Should do a roll race next to see what differences there are then

Awesome comparison video.. can’t get much better for the real street user!!

Great job, I know it's hard to do the exact same sequences to fairly test both ecu's. The difference in the Lap3 falling off on the later runs could be due to a number of factors (stock ecu interfering differently, heat soak, even the humidity / air temps being different from the time you ran the jb4 vs lap. Either way, excellent work!

Thanks for the comparison video. Looking forward to see the widebody. Keep the videos coming.

Man Im up in Milwaukee wouldnt mind chilling with you guys and the Kdmke guys

Dragy results are either valid within 1% downhill or invalid. All lap 3 runs were invalid aka downhill while jb4 were valid and slightly uphill. To be fair you would have to run the same direction over the same grade.

Good video Anthony! Keep them coming

Great video, but from experience standing starts aren't the best way to compare differences as the launch can affect the result, a better way is a rolling test, say 30-100 or 60-130 and the best way in may opinion is to do the test in one gear, say 2-nd or 3-rd gear (test acceleration between speeds that correspond to rev range 2000 - 2500 rpm to rev limit)

I'm finally going ahead with one and will go with the jB4. Check out my current 1/4 mile runs with my Stinger GT

Great comparison, I am JB4 WMI stinger and I love it.

THIS is a GREAT video Vivid, nice work

스팅어 차량 튜닝을 멋있게 하셨네요..Goood~♥

Great Video.! This was interesting to see a honest test of two comparable performance products for the stinger platform...

Great video bro 👍

This is cool. Someone needs to do one for the 2.0 as well I’m kinda interested in what can be done with those

Will be classic in 20 years

It's not only about 0-60 man that people go with different piggyback tunes. It's the driveability, the way it delivers it's torque, mpg etc. Some people might like the "slower" tune, even if it's only by .2 seconds slower to 60 but it might be better to live with day to day. No stuttering, no off idle stutter, smoother delivery etc. With that said, i love these cars. I have a scatpack charger as my 1st choice to get as my next daily. But a deal falls through, then the stinger gt is my next choice.

Hate to see you're getting rid of your Stinger as your channel helped me out a lot with my purchase and aftermarket decisions. I came back to this old video because it made me indecisive on JB4 and Lap3. I figured I'd start simple with JB4 and if I wanted more I'd go with Lap3. I just installed it yesterday (test only, since my plugs aren't in and haven't gapped my stock ones.) and was running between 4.19 - 4.26s on Map1 using 93 with a 0.88° incline. My only mods are a K&N intake and Borla exhaust on a 2020 Kia Stinger GT2 AWD. I wonder why my times are so good right off the bat?

Thanks for the comparison! Important question: Did you do a set of runs with neither? You also already have intake and exhaust upgrades which can make a difference. I don't know, all in these times aren't drastically better than the stock times put out by the various outlets. It's a decently quick car straight from the factory.

Excellent video. I hope to see more product review comparison and every car.

Did the JB4 have the fuel wires connected too on the grey car ? Great video ! You're probably getting heat soak. The 4.1s is interesting though... Would the JB4 have had similar results with the slightly late launch control ? Thank you to your whole team for this video, it's really, really useful !

The Stinger is a big girl that can dance. And unlike the competition who like to designate their cars with letters and numbers. This one has an excellent name. “Honey, lets go out in the Stinger.”⚡️⚡️⚡️👌🏻

Where are all the Chicago/ burb youtubers at??? We need a meet!

What does the car run without these devices? Also any other modifications? I have a Golf R 2017 with a JB4, it made a huge improvement on that car. I also did draggy testing and stock it did around 4.5-4.8 second 0-60 at 13.1 1/4 @105 MPH. With just the JB4 and nothing else it did 4.0 second 0-60 and 12.4 1/4 at 110 MPH. With just a high flow cat DP, bigger inter-cooler, and K&N drop in filter it now does 0-60 in 3.6-3.8 seconds and 11.9 to 12.0 1/4 mile @ 114 MPH. I am very happy with the JB4, I cannot see paying $600 more for a different plug in device with more or less the same results. If anything the JB4 seemed a lot more consistent which is a good indicator for reliability. I don't know this other device or what it might offer for double the price but it doesn't seem to be worth the added cost. The JB4 has been used for years on other platforms and has an excellent reputation for reliability and customer service. Plus they have the blue tooth option where you can log data, read codes, fine tune boost and fuel, and monitor engine parameters.

Thanks for the comparison vid!

Hey man, quick question... I have a GT2 with a tune box on the way. Did you upgrade to higher performance (ie Iridium) spark plugs and if so, what did you upgrade to?

I would Love to see this compared to a Tork Motorsports ECU Tune Stage 1! Maybe you guys could do a video collaboration or something? Maybe not? Anyways I Love your videos, Great Job! Just picked up my Stinger last week!

Thanks for the brief comparison.

Great video, JB4 is definitely going on the list 🫦

Great comparison, thank you!!

man I miss your channel!

YOU should of 0-120 or 40-120 for the guys that like to do roll race. To squash more doubts on any comparisons.

Good, no-nonsense comparison. What other mods are on the car? Intake? Exhaust? I've been considering leasing a Stinger. Would I be able to use the JB4 and remove it without detection (assuming I don't screw something up)? Is it even worth it on a stock GT1?

0 to 60 is very sensitive to conditions/surface/tires/ Temps. There is just too many confounding factors to measure a tune based on that. A roll race would take care of most of these problems and gives a wider window for comparison. I am disappointed that you do not know this already. If you are into tuning you should be aware of this.

Are the tunes intended for stock versions of the Stinger? Your car has aftermarket performance parts, so wouldn’t that cause different results?

Your follow-up from Iraq, and I have a RU-vid RU-vid special for cars, I hope to experience racing together

LAP3 is best for the KDM market.

Great video, thank you for the information.

Waiting for your cinematography with gangster gang✌

Appreciate the effort but the testing itself is a little misleading. First many customers do run JB4 map3 on 93 octane, but more to the point the JB4 runs were up hill while the Lap3 runs were down hill. That's going to make a huge difference in the results. At the end of the day both tuning systems have similar tuning potential although the JB4 offers more features, lower cost, easier install, and a wider network of tuning support.

Very interested in the jb4. Would I be able to get away with the stock intercooler? My current mods are injen intake borla exhaust ark mid pipes.

I like this video!!!

And then another thing you should have done was since there is such a big price difference. What is the 0-60 time with the e85 on a JB4 and is that still cheaper? Doing all that than it is getting the lap three because right there would be everything you would most likely achieve faster times by far than a lap three by itself and I bet it's cheaper

Heat soak on the second tuner could have been an issue too. But that’s crazy for almost double the price and you get half a second faster launch? Not worth it if you ask me

Now time to do the brake mod and see how low that 60’ goes ;)

We are bacccccc🔥🔥🔥🙌🏾🙌🏾🙌🏾

Great video, thanks for the street comparison. Both cars look and sound amazing!

You were over a 1% downslope on the lap3 pulls and like 4 percent downhill on another lap3 lol...you were a slight uphill on all the jb4 times

What front lip spoilers are on poppa stinger, I need those

What exhaust setup are you running, that sounds so good.

The Lap3 ECU Tune stage 2.5 is miles ahead now in 2022. (Not pro-tuner...ecu tune)

what exhaust are you running? sounds really good

Is it not a good idea to use a piggyback tune if your car is your EDD? What map can you run the JB4 on with only 91 octane?

How is nobody going to mention that the JB4 runs were all Valid with minimal slope. And all Lap3 runs were Invalid with crazy downhill % slopes.

What issue with your test and all that time you guys spent doing it? You never noticed that the JB4 had valid runs each and every time and every single run with the lap3 was invalid. In fact, you had a four percent grade downhill in the one run your quote" best time was over 1%. Like I said every one of those runs with the last three was an invalid run. How is that possible? Where you going to different way invalid means they would not let you load that up to the actual site on draggy. I'm just not sure how you guys miss that

lap3 test are on more downhill than jb4 . that would havs effect on the 0-60 forsure.

where is the Racechip? Racechip vs Lap3 V2 can be really nice Comparision

Did you guys run these tests using an external GPS or the GPS in your phone?

Warranty 🙈🙈🙈🙈🙈 How can you guys do all this will your warranty still be ok or is it all void??????

They recommend doing a dual oil catch as well. Was this done??

So from some comments it looks like JB4 is a pretty good tune then for Stingers?

please do a video on papi's stinger. im about to do my white stinger with a black roof and powder coat rims

Awesome man, what app you using?

Wait!!! Before watching let me like the video.

Can we see a ecu tune next?

Bro can you provide a link for the exact window guards / vent visors / wind deflectors. Whatever you wanna call it. I love your videos BTW but I need those in my life!!!

engine getting hot

Why do people wrap their gas door a different color than their car? You don't want the gas door to stand out. I don't get this.

The car needs a driver mod smfh.

This is such a nice car I dream of having one 😁

What is the App your using on your phone to track the times ?

Try the tork motor sports spare ecu

I don't get the E symbol.. I'm told it's a Kia thing, but it's not a K or S or anything really ?? If I change mine, it'll be to say Stinger or GT.. Nice Runs !! I don't really race it and want to go to the track starting coming spring 1-2 per year just for fun.. so iffy on if I care about getting tunes and stuff... not going to use it every day.... do they have eco modes that actually save you even more $$ on fuel than stock ? if want to use that mode daily ? those savings, if enough, would at least cover the cost... can you take it off easy if have to go in for warranty reasons ? will dealership know if you've had one on and give you trouble for any warranty ?

hi I'm thinking in getting JB4 for my stinger every one says its the best.i noticed you're using your phone to set maps etc. did you have to buy the JB4 Wireless Mobile Connect Kit -- in order for the phone to work with jb4?

Probably won’t get a response. But what exhaust is the car running?

Isn't this car 4.7 0-60 stock? What's the point for 0.5 seconds?

4.275 map 2

93 octane is kind of hit or miss in my area. Are the 91 Octane tunes with supporting mods (intake and full turbo back) going to get solid numbers?

Jb4 is constantly good

The Kia can not build boost unless you lots of ecu tuneing. But you my build more boost than an stock Kia like I have because of exhaust and upgrades you have.

What did you gap your spark plugs to run the Lap3 and JB4?

Kinda sus. Each dragy run the slips is different but they are launching in the same place. The runs are also invalid cause they aren’t flat

Doesn't jb4 tunes blows motors after a longer use

What kind of color is your car paint sir? Thanks for the video!!

Should compare this to unichip

every single one of your LAP3 runs had WAY more downhill slope than any of the JB4 runs and was marked invalid by the app.....

You got a new Tinder match 2:41

JB4 won the race

I love my GT.

Any long-term opinions about these?

Where you at in CHGO? I'm from New Lenox but live in AZ. Flying home May 22nd to see family but wanna buy a 2018 Stinger GT2 Red. Just gotta sell my VW CC-Rline 2015. Mint condition 24,500 miles.
