with my damned PFS PMS? I have it set at 12psi but boost will fall off to about 11psi at the top of each gear. But every time I start to take 4th to redline around 7200rpms I hit fuel cut. I just added alot of fuel to it but have not tested it. I really hate having my car hit fuel cut, how do I fix it?

 

do you redline 4th much lol?

I don't have that ecu but I'd say it doesn't have to be fuel cut only
it could be grounds or coils or plugs....I had that happen once where the car was stoping at around 6500 but then it went away after letting the car cool for a few minutes on the highway. Maybe your intake temps are real hot?

 

I second Rikki's suggestion. Relocate the knock sensor and the problem goes away.
