just have the actuator set so you only have to stretch the actuator a couple of mil to get over the wastegate.then take it up the road and see what psi it is running,then adjust the actuator to your desired boost level.shorter is more boost longer is less boost.If i remember correctly one turn is one psi.are you upgrading the turbo aswell?or was the t34 already on?because if you have changed from t3 to t34,i would run slightly less boost until you gety everything checked on rolling road good luck
