Mercedes C63S AMG 4.0TT MY2018

We absolutely love the colour combination on this beautiful AMG!
But what we liked even more was the 125wkw midrange power gain after a custom Etuners Stage2 ECU calibration. This car measured @ 306wkw with the stock map and secondary cats removed. Then a massive 388wkw after our calibration on the Dyno. Very impressive numbers for a simple exhaust modification and tune .
