Hello, we have recently changed from our beloved ABT-chipped A3 to a Mini Cooper S convertible (BJ 01/06, 170PS). Due to the high weight (1.5t) we are thinking about an increase in performance. For the Audi/VW group I mean to know the well-known tuners (e.g. ABT, Wendland, MTM, etc.). For a mini tuning I do not yet have any transparency, which tuner is to recommend. It is important to us that the tuner does not have God and the world in his program, but has itself s Also interesting would be ODB tuning. Are modifications to the compressor always necessary? Furthermore, we would be interested in how to optimize the beautiful sound still something? Thank you for your feedback! Greetings from a mini frishling…
