The waste gate actuator probably needs to be adjusted. Turn the end onto the shaft more so it is putting less pressure on the wastegate puck. This will allow it to open more easily and should allow it to run lower boost.
Now if it is holding your set boost until higher rpm's, then goes up, that is boost creep and you need some porting done. Either QPR or myself could do that.
