whats holding me back at 15psi?
ok it's a pt cruiser turbo, mopar stage 1 , hardpipe kit, 3' dp highflow cat, 2.5" catback, wideopen muffler.
before the exhaust i was holding 15psi, and after the exhaust it's still 15psi, so i presume the computer is kicking in, what do i need to fix this (map i presume?) and will it be reliable?
Punch
