Last night was driving fine and then the turbo went psycho on me a overboosted like crazy. I shortly thereafter pulled over and heard a ticking/tapping sound which was decently loud. Let the car sit for about an hour and then restarted sound was there. Got it home and the noise wasnt as bad. When the engine revs tapping increases and when the throttle was released no tapping. I'll try to get a video up here sometime soon. Just wondered if anyone had any ideas or would have a chance to look at
