Running lean (12.5:1) above 5500rpms

Yea, turning the boost down for now, just figured I'd give it a shot I'm actually surprised at how well the car runs with the 7M electronics, I have to pull the EFI fuse at reset the ECU at every fillup because of the variability in E85 mixtures, but it adjusts quickly and runs well after a few miles..

That is very impressive actually. I always wanted to use 7m electronics on a 2JZ swap and it might be my next project! So how much hp are you putting out on your current setup?

Haven't dynoed, but I'd estimate 400-450whp at the 19psi I'm running right now. I ran a 13.2@110 at 16psi and picked up ~30mph in the 2nd 1/8th so it pulls pretty good on top. Can't beat it for the relatively small amount of $$ I've got into it

It'll hit fuel cut, just doesn't get any richer afr wise. Not sure if that changes things...

Bumped the fuel pressure today and the AFRs on top look good now, even at higher boost. Got a couple other projects to jump on but hopefully I'll get back to messing with it in the next couple of weeks.

how much fuel do you add before you hit fuel cut?

The car is fast as crap, to me at least, but still streetable (assuming spinning the tires in 3rd is considered so) so it seems like a good stopping point

What rear end gear ratio are you using?

Sounds like fun Josh. Congrats.
