hey everyone.
pretty much the cars been running pretty good with the almost standard exhaust just decat and straight through mufflers, i also have a front mount, pod,cold air intake,boost controler.
its been running 10psi on that setup and running 13.67sec at the track no problem at all, then last week i changed just the cat back still running good, then this week i get a dump and front pipe thinking i would gain some power and it wont rev over 4000rpm under boost without just splutering and just running shit, not r&r either, i have felt that when i went over 10 psi with old pipe on.
so is this just the standard computer going stupid because of new pipe? or should i be looking for somthing else before i book it for a tune and put the power fc in?
i also have ngk coppers gapped to 0.8 and new coils.
one more thing do i need to change fuel pump to run 12psi on stock turbo when i get it tuned?
