Who is doing the tune Simon?

If the clutch is starting to show signs of slip then the new tune will only make that more evident with a E85 tune. It also may just be in your head too, I can definitely say I have heard sounds and felt vibrations when I think there is something wrong.

If the car still has a stock clutch and you have intentions of taking it to the track it would not hurt to have a beefier organic clutch to take the abuse.
