Affalterbach based tuner mcchip-dkr has a proposal for those who ‘lust for power’ and consider that the output on a standard Mercedes C63 AMG in insufficient.
They offer a stage 3 conversion which includes an engine software optimisation plus a remote controlled exhaust system from Cargraphic which incorporates a header, a middle silencer and a rear silencer. These upgrades enable the mcchip dkr Mercedes C63 AMG to increase output from 457 HP and 600 Nm of torque to 583 HP and 692 Nm, so as a result the Vmax electronic limiting has been increased to 310 Km/h.
At the exterior the German tuner added a touch of uniqueness by fitting the car with a set of black matt 19-inch wheels from Cargraphic which are wrapped in Michelin tires size 8,5 x19 ET47 tires at the front axle and 9,5 x19 ET65 at the rear axle.
The mcchip-dkr performance upgrades carry a price tag of 10,000 Euro while the wheel set costs 7,473 Euro.
