Since u have a Rev.2 with CANbus, that will be easy to do.

i have only dci. the spark plugs are new (~2500miles). with ut 80% all is okay. no misfires. then i run higher ut (85 or 90) the engigne produces misfires at higher rpm on different cylinders. not always but i can wait for. especially at the autobahn with continuously higher rpm (over 4000).
i'm using only ROZ 100 Gas (Shell V-Power). i dont know the comparable gas in u.s.??
