Mercedes-Benz is best known as a luxury automotive manufacturer, but they also produce some of the best high-performance cars on the market. The C63s, specifically, combines the best of a relatively small luxury sedan and an extremely high-performance engine.

Under the hood of the W205 C63 you’ll find Mercedes’ well known and loved 4.0L bi-turbo engine, outputting over 500hp and 500lb-ft of torque. Although that an insane amount of power, it’s relatively mild compared to what the engine is capable of. To help introduce their prospective customers to more expensive vehicles, Mercedes-Benz holds the performance back on the C63 and C63S.

All of this hidden performance can be uncovered and tapped into with a simple ECU tune. By changing the parameters which the engine operates within, power can be massively improved without sacrificing reliability. In the case of the C63s, our VR Tuned ECU flash increases power by 60HP and 114LB-FT!

Aside from the huge increase in power, throttle response and fuel economy are improved. For those who want even more power, the Stage 2 file offers more horsepower and torque. On top of that, our VR Tuned ECU flash is designed to work with bolt-on modifications and the tune will adjust itself accordingly.

  • Stock: 510HP and 516LB-FT
  • Stage 1: 570HP and 630LB-FT
  • Stage 2: 596HP and 658LB-FT
