my fly hasnt been changed either, just the clutch and PP, and Jay is reporting odd noises from the clutch area of mines. Mark had the clutch and PP replaced with an Exedy 30% uprate item, all he needs for now, and is gettin definate vibrations, so perhaps not identical to Bill's issue, but could ceertainly be related. mark's is happenin both on and off boost i believe. its the oddest fuckin sound when your in the car, but its not as loud as Bill is describing his to be.
