So, to give you all a little background, I just got done with my turbo build and after taking it to Ed on Friday for a 4 hour tune/dyno session, I left VERY dissapointed!

First...the setup

H22 Bone Stock
Garrett T3/T4 .57 trim .60/.48 AR
HKS BOV
Turbonetics 38mm Wastegate (7psi)
RC 650cc Injectors
Walbro 255lph
Large front mount 2.5'' piping
2.5'' downpipe & 2.5'' open exhaust all the way to the Apexi muffler
No name tubular manifold

So after 4 hours of tuning with Ed, I was only able to put down 240whp, and the power just dropped off at 7400 rpm. It seemed like the car wasnt getting enough air or was having a problem geting rid of it. We were both really dumbfounded when we could only squeeze 240whp out. Ed stated that he pulls 300+whp out of stock h22's on 7psi quite often and he didnt understand why this one wasnt.

Does anyone have any ideas or has anyone incountered this as well? Why would the car just quit making power at 7400 rpm? The turbo spools up really quick but then just seems to die out. I dont know, I'm just really frustrated with the outcome, so any help would be greatly appreciated. Thanks
