look bud , stock solenoid wont work, Atr43g3 turbo if its new it will open waste gate at 18psi( if not it will open at 15psi ) , If you attach the standard solenoid it may stuff your car, the stock solenoid originally worked off 5 - 7 psi . Honestly if you asking this your going to be like me and stuff your car!! remember original waste gate was about 7 psi
