Controlling high boost in third gear.
I have a wastegate manufactured by applied technologies, the boost is easily regulated in first and second gear at 15 pounds, but whenever the car moves into third at wide open throttle the PSI immediately goes past 20 pounds. I have tried changing the Spring to a 10 pound and a 15. I have even cut one of the springs in half, and I can still run over 20 pounds in third.
I have also replace the diaphragm. I have checked actuation using my air compressor, is it possible that the wastegate is too small for my PT 51 Turbo??
As the weather becomes colder the issue becomes worse.
My next step is to remove the inside of the wastegate, and see how much boost is made without the valve and place.
Any help would be appreciated
