German tuner Mcchp dkr is keeping busy these days. After the Porsche GT2, they turned attention to the mad Mercedes C63 AMG.

The engine tuning recipe is simple. They just tweak the ECU software a bit, and install a full Cargraphic sports exhausts system consisting of headers and new silencers. The result of these cchanges is a huge ump in power from 457 to 583 PS and the torque from 600 to 692 Nm. With this much power under the bonnet, the C63 can now reach 310 km/h electronically limited top speed. The engine package costs 10,000 euro.

You wouldn’t be able to tell this car apart form normal C63 based on the looks though, because the only features it gets is a set of matte black 19-inch wheels with 8,5 x19 tires at the front and 9,5 x19 at the back. The complete wheels set costs around 7,500 euro.
