In the case of German tuning firm Kubatech, the answer to the C63 AMG’s horsepower problem was a Stage 3 performance kit that includes a new ECU from Mcchip-dkr along with a complete sports exhaust system from Cargraphic, which help bump output to 583HP and 692 Nm (510 lb-ft).

The engine upgrade is accompanied by a new set of 19-inch alloy wheels in a black matte finish, shod in high-performance Michelin rubber.
