Well I always run 20 psi not any more. I know my fuel system cant hold more than that. I have also been leaning twards a valve spring going soft. Im going to run a return line this winter and switch out my fuel pump. Hopefully that will do something

I did correct the problem. I ended up having a 60% blockage in one of my injectors. I swapped the RC out for some deatchwerks and I havent had the problem since

o ok. nice. i found out my tune was really jacked... i clamped to 11.6... when this started happening.. i decided to remove the clamp... my afrs were at 11.9 with it removed. i think i tuned it in a rare environment..
