hello.. how far does the wastegate open when the required boost level is reached.. im guessing only a few mm on my t34 after removing the actuator arm the wastegate was hard to open by hand and was wondering how much pressure the actuator arm has to push this open?? when i took the turbo off the car i think the arm was bent so replaced with another turbo and after 100 or so miles this one seems to have tightened right up.. ? any help please..
thanks
