Sounds like the problem I had for a month. My car would not boost past 4-5psi. Erick and I checked EVERYTHING. Fixed a **** ton of boost leaks, pressure tested to like 35psi, bypassed the boost solenoid, and even clamped the waste gate closed. Still only hit 5psi.
I noticed a rattling in my exhaust, I thought my flapper valve had broken off and was rattling around in my exhaust. So I pulled the cat off and behold, my hi-flow cat was completely destroyed. It looked like a layer of it had broken apart and completely clogged the rest of the cat up. So I hollowed the rest of it out, bolted it back up and went for a drive, with the waste gate still clamped closed. It's a very good thing that I have a boost gauge
Boost is back after the cat was cleared!
anyway.
Check your cat perhaps.
