I'm obsessed with the F80/F82. Can't stop thinking about M3 vs M4. DCT vs manual. Factory competition pack vs personal customization. Your videos have been very helpful.

I have a 2017 F80 Comp w/ Dinan S1. It's pretty fast. With rear wheel drive you can't make much use out of any more hp. It's a monster on the track, once the tires are hot. On the road you can't get them quite warm enough. To add to that, I live in Vancouver, where it rains all of the time.

Been a Honda boy all my life. Recently been eyeing the M3s and man 550+whp on a tune and down pipes is crazy. Then again it is twin turbo. Going to finish paying my CTR and getting one after. Great video.

I have a 2015 f80 M3 with no downpipes with a custom tune and a front mount cold air intake I had consistent runs of 509 whp and 550 wtq

Great video Tommy L! Very informative. You are the first to put up the comparisons between stock and JB4 that in my opinion are not flawed or designed to sale a product. Keep up the GREAT WORK! Already have the JB4 tune but haven't installed the downpipe. Video takes away the guesswork and JB4 is worth it due to customization.

420 at wheels stock is pretty darn nice.

Nice video. Was fun that night see those cars on dyno

Another great video very informative. The only variable you are not accounting for is transmission. Manual cars always dyno higher than dct cars which is probably why your stock car ran a higher number than his DP only run.

Thank you for the comparison. For me, the tune and something like an axle-back or DPs isn’t about GAINZ, but about knocking the dust off the factory-tuned setup. These cars just *feel* better with a stage I and a sound mod imho. In short, totally worth the minute risk.

Tight vid bro! Logically sound hp gains.

Thanks for the video. I proudly own an F80 M3 with Upgraded Charge Pipes, Downpipes, Burger Intake, and JB4 mods. Have always wondered what numbers I could likely expect on a Dyno. Estimated somewhere around the 490 whp on MAP 2 based on log runs from the JB4. I want to upgrade the exhaust but don't think that I will get much of a performance upgrade at this point but more of an auditory upgrade over the stock exhaust. Very interesting video to me and excellent job.

Hi, Tommy been following your channel for a while now & decided to chime in to inform us, viewers. If you're using a piggyback like a JB4, they can't tell you had it on if you remove it before going to the dealership. How can that void your warranty? And the JB4 map 1 gives you about 4 psi of boost, while map 2 gives you about an additional 6.5 psi. Map 2 is safe to run with downpipes as your EGT doesn't get as hot. The S55 can handle close to 22psi before having to upgrade the turbos on FBO. Which means if you upgrade air intakes (which gets rid of the air boxes and sucks more air), downpipes (lowers pressure and decreases EGT), charge pipes (gets rid of that narrow plastic to increase flow), and exhaust (gets rid of more back pressure for more power up in the RPM >5400), then you'll get something closer to 540 HP. Anything higher than that, you'll need to upgrade the turbos. There is no way you can make 562 HP stock turbos on a 3.0 displacement. Ask the dyno guy if that 562hp-595tq run was on stock turbos? If he says yes on stock turbos, you're looking for a disaster waiting to happen. And as for a custom tune for $2,500, I would run so fast, Bolt! couldn't catch me. I would go with bootmod3 ECU tune for $700; the feeling would be so much better than a piggyback, as it'll be controlling more than boost. You'll be pushing close to 470 HP without any modification to the wheels. Then move up from the OTS maps, and custom tune it yourself if you know how to tune or pay a tuner ($200-300) to tune it to your car (mods, gas, etc). You can also which maps once you unlock your ECU. So let's say you're going to the track and want to put 100 octane, then switch maps for more power. If you want to put e85, you can switch your map and gain another 30+ hp on top of the increase you're making now as e85 has a higher octane level. It's all about pulling the right timing depending on what gas (octane) you use. This will determine what boost to target at what load (DME tables). And you don't have to pull the ECU out as everything is done through the OBD2 port. If you had a DCT, you can also upgrade the software on the transmission to the M4 GTS, which can handle more torque. And the software is also included for the $700. Also Ray higher base torque curve attributes more to the DCT than the downpipes. Anyways, that's my 2 cents. Thanks for the videos.

Informative video! So your next video shows an installation of a JB4? ;-) !!!

Very impressive 424 bhp at the wheels around 475 bhp engine/crank stock is really good.

Yea u cant go wrong with the jb4 i just started using it and its definitely the most bang for buck mod u can do on any turbo car

Exhaust sound reminds me of E46 M3

I’m watching all the old Ray videos lol

Def makes me want a manual m3 more than a dct m3 even though it’s barely noticeable lol

Dam dog is that kaneu reves at 2:27

Was waiting for this video

Finally i can see how much HP&Torque jb4 can actually add to my 430i GC 255 stock about 337/340 hp hhhhmmm with the same set up as Rays car DP cai & JB4

Great video well done

You know simply adding a little more boost won't void your warranty. Unless you have it specifically in black and white(which i doubt)

I’m gonna have to get mine custom tuned.

Great video. Jb4 increase torque for sure but in not that much improvement in horsepower. Good to know that. 👍🏼👍🏼👍🏼

Thanks Tommy for answering the question FB couldn’t answer 🫡⭐️⭐️⭐️⭐️⭐️

That's the 1st American I've seen that can change gear in a Manuel properly

amazing video!!

Great video! no downpipe needed, just needs bootmod3

He’s gonna need a larger intercooler or a larger heat exchanger to keep that power in the real world outside of a dyno pull.

Good comparison!

Well just the jb4 map 1 doesn't void warranty if they don't know? I assume the down pipes do... if nothing ever goes bad on the engine and or other parts then yes, very worth it. Lol

Great video. Can you give me the turners information? I would like to have me car tuned.

Well done man! Let’s meet up soon, weather is finally about to break!

big reason in whp difference btwn dct and 6spd is boost lost between shifts tuning should almost eliminate the issue

Just go with a dinan tune.

Bought my GTI a year and a half ago and in 5 or 6 months voided the warranty with a tune and never looked back lol. Crossing my fingers I’ll never need to use my warranty. On the plus side though, the dealership I bring my car to is “tuner” friendly lol. I did the JB4 first and was happy with it for awhile. But then went with a custom tune via accesport

Can you put the numbers in the description?

Wait so the boost increase tune at end gained 8hp but lost 44 torque? Come on who would ever want that. The 44 torque would make a world of difference over the not noticeable 8hp

Yeah men Great video !! advice learn how to make some cinematic lock footage it will be awesome

Just has to be said true only 50hp but he made 100ft lbs of torque more and that's what will win a race at the end of the day

Curious to understand why your horsepower numbers are higher than torque? These cars normally generate more torque than whp. I dyno'd 396-400 whp and 405-415 ft/lb on 70 degree outside temp w a/bad MAF sensor and leaking intercooler.

Tommy, how can I get a copy of the custom JB4 map that you guys were using in the video above?

Nice video Tommy, what exhaust tips are you running?

Did they test in 4th or 5th gear? 5th is 1 to 1 in both transmissions. 4th gear isn't the same between them.

Which alloys are you running on the manual M3, they look amazing. Where are they from

💙💛💚🧡 Awesome 💙💛💚🧡

I have seen auto 435-440

hmm the numbers kinda low for the JB4 with downpipes , any reason ?

bootmod3 all day. jb4 is too inconsistent when you pull up a data log during pulls.

Who would run caveman tech jb4 in an f80....wayyy better options

Jb4 is enough to use, no need a custom tune

what fuel was that on the jb4 car.

Why not just get a dinan tune, from what I believe those don't void the warranty.

I read that a zcp m4 with downpipes should run map 3 over 1, true?

how is that possible 562 whp cant be real? with custom tune

I thought the stock M3 Comp was supposed to make 444? Really thinking about tuning but I'm also afraid of voiding the warranty

Something is up here. I put mine on the dyno with a JB4, exhaust, BUT NO DOWNPIPES. and i was at 547whp on map 7. why was his so low? i honestly dont know.

Wow shocked if that's real ain't the comp package like 440 ish at the crank how in the world is it only losing 20 hp to the wheels. Cant say for sure but dam that has to be a very generous dynamometer. Not sure how the m3 could be that under rated from factory. Just as an example the dyno I go to a stock dodge hellcat with no tune will put down 635 whp 600 rwt with a bit of push pull on either side seen a little more and less from a dyno jet dyno and those cars come stock crank 707 hp 650 tourqe

Is jb4 worth it?

Have you dealt with bootmod3, if so do you have a tutorial vid of it?

Even 400 HP is plenty

What type of air fuel ratios were sering with the jb4 and what was the air-fuel ratios with the custom tune?

Jb4 doesn’t void warranty

so does that M3 have a turbo or supercharger on it, you did not say, well i didn't hear it or missed it.

you dont lose warranty whit jb4 and downpipe ?? thanks

sae rated number or standard?

You cant compare a manual vs automatic car...

is this on SAE rated or standard?

How does it come that almost all the M3’s non competition in germany pull ~440 - 485whp stock?

2500$ lol lord 🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️

geez, tough one...

E85 it and do another run

Auto is much faster than manual. No comparison

Hi do 420bhp at wheels. Do you know what that relates to in bhp at flywheel. ?

JB4? Its 2019 you better BootMod3 that thing

what type of fuel was you running with the JB4?

DCT > MANUAL. In terms of speed and power the DCT is better this “professional” should know that🤦🏾‍♂️ there is no human in the world that can outshift a DCT
