I've got a 3 inch TID w/ cone filter, FCD, Walbro, MBC, Downpipe, and TB mod.
At 5k rpm i hit 10 psi, but then as i hit 5800 it drops to 7 psi and at redline i'm hitting 5 psi. I know that the boost dropoff is normal, but its worse than it was when i still had my cats in. And you notice the car doesnt seem to have much pull past 5k rpm. In fact, i feel a noticeable loss of power. Any ideas? It does this in every gear btw.

Sounds like a vac leak.
My car did the same thing when I went to track and it pissed me off because I shouldve been running alot faster than I was. Next day, took a look at it in the day and one of the couplers slipped off. IT SUCKED.

Boost dropoffi s the same for all gears. And, as to what mike says, i thought you have tow orry about boost creep with mods? And my boost is dropping off a lot. It's really frustrating and feels like i've lost half my powerband. Anyways i'm rippin everything apart and am gonna put it back together again this weekend so we'll see then.
