ive been impressed with revo on the ED30, and those claimed gains for the GTD will put you on par with a standard GTi
the increase in torque is huge and will hopefully give you that zipiness back that you are missing
i believe VWR in Milton Keynes are now Revo agents so hopefully you can retain your warranty if you go with them.
Would still wait a few thousand miles before mapping - get it run in first - 900 miles is too soon to start jumping to conclusions
it took me 5k miles to get use to DSG, I hated it at first and thought about swapping, but after giving up on D and S and using the paddles all the time i have adapted and now love it
