Boost too High
Here's my mod before Helix CatBack and P2 Brain Wash. Then over the weekend I had my downpipe and my cat replaced with 3" pipes, on the way home from SCCA i noticed that when in 5th gear WOT i noticed that the car kinda bogged so i let go of the pedal and did it again this time watching the Boost Guage i noticed that the Guage was dialed at 1.5 and hang there den i noticed it bogged again so i stopped doing WOT with my car, my question is since I changed the exhaust will it affect the boost also? do i need a reflash again? or reset my P2? Is this unusual or normal? can someone help me? thanks.

But to answer your question, bring it back to WORKS to update the flash with your mods. I just had my P2 updated for a highflow cat / test pipe,cams and turbo back and now my boost holds at 1.30-1.35 BAR
What they are saying. I had my ecu flashed for cat back only and as soon as the weather got cold I was hitting some high boost. 25psi once! so i was in the market for the aperture anyway, so i got that and had my ecu properly flashed for the full exhaust and now i'm fine. no more boost spikes and things seem a lot smoother.
