Anybody else running a turboxs type H? I have 3 shims in, and it seems past 20 PSI it feels like it's leaking because I can hear it fluttering like it's barely opening and closing real fast. 3 shims seems like an awful much already to only be holding 20 PSI.
Anyway, what I'd like to know is how much boost you are running and with how many shims? Or especially cases that it started leaking on you at XX amount of boost and then you put it X amount of shims and it fixed it.
