Hey guys,
Is it "normal" to hear a whistling noise under hard acceleration from the engine with JB4 on Map 2? I'm guessing it's actually coming from the turbo spooling up. It sounds like a whistle that goes from a moderate to high pitch for like a second when I punch the accelerator.
I don't think I ever heard that noise before the JB4 install.
