damn i havin the same problem bro but mines fall on its face as soon as the boost kicks in. i hope u get it figured out cause this one is kicking me in the ***

 

Hey, I know this is 3 years old, but did you get everything figured out? I've been fighting this same problem for a while now. I've gone through injectors, distributors, fuel pumps/filters, engine management systems (from tuned on ectune with a chip to neptune RTP).
It feels like there is a boost cut, but there isn't. Looking through the datalogs, a fuel cut never gets turned on. I can pull through the rpm's at 70% throttle, but as soon as I hit WOT the car shuts off. AFR's are in the 11.7-12.0 range immediately before this happens, on 8psi.

 

What cams?
