I have read most of the threads about SuperChips Bluefin.....and they all seem to confirm that it is a good idea? But there is hardly anyone who confirms that it still a good idea after driving with it for 12 months? Can anyone give me feedback...problems etc? I'm thinking of get my 2.0 TDi Bluefinned but would like to know that in say 12 months time i will still be smiling!!!
