I have a turbonetics Deltagate 2 and it sticks open after i get on it about one time. It is set at 7psi and like i said it will get there about one time and then I can only get about 1-2psi after that and can hear the exhaust constantly exiting the dump tube. It must become unstuck when it cools down again because after it cools down(turn the car off for awhile) I can get another single boost out of it. Anyone had this problem with this wastegate before? anything you think can be done to fix it?
