The last couple of days I seem to have lost some mid range "power". It still seems to pull like a beast from 5,000 rpm onwards, but seems flatter than it used to in the mid range. Could this be the supercharger clutch going, or could it be that I have had loads of town driving for a few days and I need to do a Throttle reset ? Also, It doesn't seem to change down so easily (less sensitive), kick down is fine.
Mine initially had a loud rattling noise on idle that made me take it to the dealer to have it checked out. They diagnosed to be the clutch failing but they had to order parts so i drove it around for a few days where i saw a decrease in performance.
