Its not slip. its LIKE slip. clutch seems to be doing its job and always staying engaged. I believe (from what i can put together between numerous guys looking at the car as well as what I’ve read about other X owners) the increased flow capabilities of the turbo with the intake/exh/uicp combo, plus a trump rich tune, PLUS a possible boost leak I cant yet detect (insert tdi’s special tool assistance here) all contribute to the “slip.” The boost leak makes most sense but a tune should fix the issue, I’m confident
