At 3,000 rpm my car, under boost is making 30 lb/ft torque less than stock and it's running 11.1:1 there. If it was leaned out in the midrange, it would act civil, make more power and get better mileage and be closer to emissions targets.

My car does make 422 whp at 7,500 rpm. That part is ok. I'm not suggesting they lean it out at redline. It's under 5,000 rpm where the tweaking with Stillen's tuning needs to occur. If you look at their press release, they are getting 340 lb/ft or torque in the midrange, where my car is only making 280 lb/ft.

seriously? you only made 280lb/ft of torque?

Dyno scheduled for Tomorrow at noon. Will try to have the results posted a few hours following. So far just doing a little initial tuning to help get the car prepared for tomorrow but so far so good.

^exactamundo dude +1 thats why I would run 12:5.1 on E85 ;-)

Id be happy with 11:0.1 to 10:8/5.1 up top on pump, depending on timing and boost, personally I have never seen an EGT guage on a Z as yet but that is soo helpful when tuning FI.

Bad news bears, we are having some tech. issues with Uprev with my ecu. The kit is great, sounds amazing, makes boost really early but we are having Uprev software problems again with my ECU. We pulled the plug till uprev can get some answers. I don't know how Chris handles this type of BS from Uprev. This is the second time they have cost him a bunch of money for software issues. He has done such a good job only to have this derail the build.
Will keep update when find something out

Yes it is fine to drive DD, it is actually a little rich in open loop or non load conditions but why drive it when or if I need power I hurt the motor and things are not running correctly. The car under any load is extremely rich 9.5:1 to 10:1. We hit boost a little and it came on early so that is sweet and makes me feel a lot better about the kit, but the Uprev fuel tables and left and right bank were going hay wire and were miss labeled. Uprev is pretty much on my **** list. But on another Chris did a great job, the kit looks great, the little boost we hit came on nice and early so I am now dying to have the car finished.

Thanks, I hate being a guinea pig. I do believe all our issues can be blamed on Uprev, that is why they are at Stillen. These sort of things make me really iffy about doing this. I am hoping Haltech has something for the 370 soon. Any updates on your car?

I thought Stillen was using a modified version of Uprev? So not directly Uprev at fault here.

We are using the normal version of Uprev, and doing a custom tune. This particular ECU ROM has a few bugs in it.

Chris is it a particular ROM ID #? If so which one?

I dont think its the kit... I think its the tuner knowing whats right. I believe he has the old pulley.
