Few days ago I see that wastegate arm is fully shortened (for max boost) but my turbo gauge still shows 0.5 bar. Maybe Amal valve is guilty for that?


When I little lower boost (with wastegate arm) car is going slow, and have little
detonations from exhaust.

End my Amal valve make click when I turn ignition on BUT amal valve after that, still making clicking- quiet but I hear it.

Is This Mean That My Amal Valve Needing Replace?

Thank You
