ok the boost on my PFC is set at 0.85kg/cm^2
i was getting 12-5-12, now its even worse, its like
9-5-9.
i have done a silicone hose job a while back so i dont think ne thing is leaking from there. at WOT i hear air (whoosh) coming near the glove box while im driving. checked all my intercooler/intake pipes and its all tight. ne ideas where my boost is leaking from?

 

crooked porting

 

Check tightness of all boost clamps.
If you are still running the stock y-pipe take off the rubber coupler between the y-pipe and crossover tube. Bend sharply as though you are trying to turn it inside out and look for cracks. If cracked replace or switch to an efini y-pipe (no rubber coupler).

 

if its not the coupler what else could it be? gonna check the coulper tonight.

 

check hoses from "y" pipe to blow off valves they always brake and leak
