I've read a few forum posts on this but can't find solid answer. When i hit turbo from 1st to 2nd gear i hear a loud high pitch sound have no idea what it is just know its coming from the turbo. One of my couplers had a hole and i lost power, the loud pitch sound vanished, till of corse i replaced the coupler and regained all my pressure back and now the pitch sound is back. this is why i say its coming from the turbo? Any help, have any of you guys heard anything like this before, can anything else be leaking or maybe loose?

Nah bro. The sound is like a loud screaming sound. Like if i have a hooker under my hood getting raped by intercooling pipes. All jokes aside though it sounds like that scratching chalkboard sound thats very loud and annoying

Are you able to hit peak boost? "Sounds" like another boost leak to me.
