This is a wierd one for me. The car is whistling almost like it has a turbo between 10 vacuum and 0. The car gets 16 lbs of boost, with 10% OD and coated rotors. I tried pulling a vacuum line to see if maybe it was a similar sound, but it wasnt. This has got me stumped like no other. It only whistles in that range while driving. I can blip the throttle when its parked and it won't make the noise. The car runs fine otherwise. But if it's whistling I would assume that it's losing air?
