This 2020 Mercedes C63s AMG came in to push performance boundaries. With our custom Stage 3 ECU, CPC, and TCU tuning, we not only extracted more power but also unlocked full rev potential — allowing it to scream all the way to redline in P/N.

The result? Sharper throttle response, more aggressive power delivery, and that intoxicating AMG roar — now with no rev restrictions.
