I have an on3 kit for my fox with a 7675 precision turbo and a 45mm Turbosmart wastegate. The wastegate has a 7 lb spring in it and at 5100 rpm the boost is at 12.4 according to my tuner. Car is currently there. We are trying to figure out what to do. He thinks it’s where the wastegate is located that it’s not able to let off the pressure it needs to. Has anyone had an issue like this with the on3 kit and did you fix it?
