I have a full exhaust on now since some one on this forum told me that on his fd a clogged cat was the cause, so I finally put my catless mid pipe on (its been sitting in my garage for a while. But still no boost past 4 or 5 psi. My mods are only exhaust for now, looking int a PFS real soon.


Tried all the stuff to diagnose the problem from various sites, but with no luck. Would a profec b help i can borrow one from my friends talon.

 

do you get normal boost on the primary and get 4-5psi on the secondary? or do you get no more than 4-5psi of boost on either turbo?

 

I know this is gonna **** you off, but I'd put a cat on the car until you can get an ECU. if/when you get the boost leak fixed, there's gonna be massive spiking/creeping and you're risking your motor.

As far as the leak goes. Did you see this site?

It has lots of good leak info, and provides step-by-steps directions for testing most of the control system for the turbos. If all of those tests pass without results, try a vacuum hose job. If that doesn't work, your turbos are the culprit. But theres a whole lot to go through before making that assumption.
