This thing is driving me nuts. Ive got a high pitch whine/whistle. Kinda like when you hold a balloon together and let the air out. It doesnt do it after driving for about 10 minutes, but if you shut it off for even a minute it will do it for a couple miles again. It only does it under load and it quits while it shifts. I replaced the y pipe due to soot, still there. Replaced the angle boot, still there. Ive got it pinned to the turbo area it sounds like. Any help its making me feel dumb.
