Hi there,

I just finished installing my procharger kit, but when I put some throttle on it just enough for the supercharger to build up some boost on i, it hesitates badly, it picks up again and then hesitates again. I also got a lean bank1 error code.

So I did a pressure leak test, and the sytem cannot hold any pressure, not even 2 psi . I push 90 psi with a compressor in the pipes and all of it runs out.
I here the air venting from around the bypass valve, even though it's closed (if I open it the sound changes and the air gets out quickly). The bypass valve is connected to a good vacuum line from the intake manifold (I checked that line also). I have the metal valve type, not the platic one.

I really don't know if it is the valve itself that leaks, since I have to take th bumper off to see clearly, but the sound is coming from there.

What do you guys think ? I'll do the full checking tommorow but just wanted to know that if it's normal for the valve to loose that much pressure, or should the pressure hold a decent amount of time.

thanks.

from what I understand these leaks are common, my car makes 11 psi on the gauge...so I think everything is ok dispite the leaking...
