If you're trying to vent the stock BOV, it's leaking, causing lower boost levels.

Running TOO RICH will also suppress power and boost.&nbsp I see some of you guys are running large secondaries - are these tuned?

i think this thread is pretty old, but the reason everyone's boost is falling off (its not a coincidence) is because the stock turbo compressor is not aggressive enough to keep up with the turbine side at high rpms. theres really nothing you can do about it, however i'm not sure if a solenoid boost controller will FORCE it to keep up or not... anyone know about that?

 

I have a same problem, before thi problem my psi are 9 to 7 and running at 7psi all time, now i lost power and the psi down to 5psi.
