Anybody have a problem with boost creep..? Is it common with our cars? I know it is with EVOs and STIs... never hear anybody in here talking about it...?

what is boost creep?

Boost creep is rising boost due to not enough exhaust bypassing the housing. For example, you're set for 13 psi, and when you floor it, you get a quick rise to 13 or 14 psi. But then as rpm's climb, the boost creeps higher and higher: 14, 15, 16, 17, etc. boost creep is one of the worst problems you can have with a turbo engine. Boost creep means that there is NO way for the boost pressure to be controlled.

never heard of it in our cars, maybe you can control it with an mbc in parallel to your n75

Not very common in our cars due to the N75. It'd have to be shot to allow that to happen, IMO.

That's what a wastegate is for.

That's correct, our car do not have issues such as this unless there is something wrong with your wastegates.

This only happens when your wastegate holes are too small, not the case in any our our KKK turbos.
