Replaced loose actuator arm now constant overboost

[guyd_15]

On my son's CSX-T the wastegate actuator arm came loose, I reattached it to the swingvalve arm. Now when ever he gets on it boost shoots to 17 lbs and hits overboost. So I installed a grainger between the manifold source and the actuator, even with the G-valve all the way unscrewed it still hits overboost and the boost didn't even drop. I checked the swing valve arm it's secure and the flapper moves. Any Suggestions?

Bumped this up. So maybe I can get it fixed for him tommorow.

Sounds like the actuator may be bad. Gently put air pressure to it and see if it moves.
