since i got all my parts together for my parts, i'm getting antsy to put this thing together and drive it!i am planning on a 57 trim but i will defiinatly not gonna have enough money to get my maft pro+wb+550's etc to really up the boost.i just wanna know if running stock boost with a 57 trim is safe?i mean if i can run 14 psi and be "safe"is stock boost pressure on a 57 "safe".also i hope boost doesnt increase with full 3" exhaust and 2.5" ic pipes.

Im running a 57 trim ct26 with a few mods but Im only boosting 12psi-13psi... I havent had any issues but Im hunting an oil issue as my car is not smoking and not dripping but consuming oil over time. Im thinking its blow by. I have to hunt down a 7mGTE to redo.

I'm fairly happy with my setup -

upgraded fuel pump, Aeromotive AFPR, Cleaned/Flowmatched 440's, and the stock AFM. I use a WB and NEO to tune it, but even before that, AFR's and EGT's were good at ~12.5 psi.

99% of the time I run 10psi, but I do dial in my high setting of 14psi every once in a while. I have never hit fuel cut or experienced anything that gave me pause.

I was originally going to switch to 550's, but since 10psi feels pretty good to me - I am sticking with that for now.

You shouldn't have any problems with what you want to do, provided everything else in your car has been well maintained.
