How did you fix your problema nd what was it?

 

I fixed mine by purchasing a turbo boost hose upgrade kit from pettit "$135.00".

 

My wiring to the wastegate control and turbo (pre?)control solenoids was crossed. I went from a 10-5-5 pattern to a 10-8-12 (winter time). I'm still not 100% though. Boost drops to 8 at around 5200-5300 RPMs and holds to redline. Not worried about it yet since I don't have an ecu upgrade to support 12psi anyway.
