Got back on the same dyno with some E85 in the tank (4 gallons on a fill up).

636 WHP 657 TQ

Pretty happy with the results considering it was 100+ degrees out. My IAT was 122 with the car cold sitting in the parking lot for a few hours - it actually cooled down after the pull by about 2 degrees!

I think given better temperatures I could easily reach 650!

Moral of the story - replace your 02 sensors and mix in a splash of E85 (if your gas sucks...)

It was at a dyno day where pretty much everything was American muscle, no one knew anything about BMWs and when my car got up there I overheard some people taking bets saying my car would dyno between 350-450. LOL.

Lots of jaws dropped. Sleeper to the max.

Here are the logs from the pull. I really don't know what I'm looking at but IAT looks good. HPFP looks like it hits 2885 and isn't moving, maxed out? If anyone can explain what normal timing should look like that would be awesome as well.

Cheers

I'm on NGK 97506, gapped to .018. I installed them maybe 400 miles ago along with injectors so basically brand new.
im getting ready to replace my plugs

the NGK 97506 is the colder plug we are supposed to use on stage 2?
and why is it that some people say gap to .020 and some .018? lol

They say to gap .018-.022.

I just went with .018 because I accidentally gapped the first plug to that so then I had to do the rest. Lol. Rocket science

.018 is for high boost applications and can sometimes cause rough idle

But if your running good shouldn’t be a problem

Also your timing looks good
