The most popular upgrade for us at the moment is the Stage 3 tune on the BMW 335D – these cars are developing big power now, and were only available with the automatic gearbox. Being able to change that box from something designed for comfortable cruising to a responsive sporty setup makes all the difference for the guys who are using these cars on the track.
