Your always going to be fighting traction as you add power so you’ll need to invest in different tires. On bootmod3 you can just adjust the torque curves in 1st and 2nd on your own in the app. For example I decrease torque by 30% in 1st and 20% in 2nd. On track mess with the torque reductions

First try, Mosselman turbo on E40.

It may have 5.5 seconds in it… I hit redline at the top of 3rd (ask you can see).


Mod list in 2nd picture.

I have run 5.64 (and probably a dozen 5.6x) at around 700whp. A 5.5X for you is definitely doable.

[BadBoostedBMWM3]

That makes me feel better^

I just need more seat time.

10 months in the making to get the car to stop pulling timing. Finally got a good baseline on my setup, also had no front bumper on the car but that wasn't stopping me.

E50 Blend
DI Only

Very good in that DA!

Please give a mod list.

Damn! I knew the EU5’s had 700whp but I did not think that they had 800whp.


You have to be 800whp with that drag coefficient being so bad with the bumper removed.

You beat my DI only best! What tire setup did you have in the rear?

Very nice.

What software are you tuned on?

on a Dyno Dynamics dyno it made 700HP/668TQ, but we turned it up a hair on the street. Still trying to dial in boost drop on shift. will test new revision once I have a bumper on

the comeback was personal after Bend said they wouldn't tune my car LOL,
I have 305/35/18 Nitto NT555R2

In my experience, Dyno dynamics always read lower if they are not being adjusted/fooled with. Every Dyno has a correction factor that can be inputted.

Like my car, put down 789whp STD and has went 5.42 in 2000DA and you are definitely stronger than me.

I agree, at the end of the day I could careless about the numbers on a dyno. I use it as a way to make sure my torque curve is "safe".

Truth!

It just area over/under the curves IF one uses the same Dyno.

5’s next time!

Awesome compilation. The level of verification and the way the list tracks mods, DA, and shifts makes this one of the most useful performance threads on the forum. The spread between turbo setups is super interesting too. I’ll share my 60-130 once I get a clean file. Big thanks to everyone maintaining this.
