Who writes your tune

Trained in Affalterbach. With MBH for 20 years.

Most tuning shops buy a generic file and resell it. Ours is written by the same person who has tuned Mercedes for MBH from the beginning. Over the years he has also worked with some of the best-known names in Mercedes performance, and that experience goes into every car we tune.

Matched tunes

Written for our hardware.

A tune is only as good as what it knows about the car. Ours are developed on the dyno with MBH headers on naturally aspirated engines and MBH downpipes on biturbo engines, so fuel, timing and boost are set for the parts you actually have. Factory safety systems like knock monitoring and thermal protection stay on.

Gains from MBH dyno testing on the cars named. Results vary with dyno type, weather, fuel and the condition of the car.
