Mercedes-Benz GLC 63 S 4.0L V8 biturbo 510hp

A real beast passed through our hands. We had the chance to remap a Mercedes GLC 63 S with the legendary 4-litre V8 biturbo engine and 510 hp from the factory. The car had already received a mild hardware upgrade with freer-flowing catalytic converters before going on our dyno. Its initial output was just under 500 hp, most likely due to its fairly high mileage. With our remap the result was 560 hp (+65) and 798 Nm (+120 Nm). The difference is felt across the whole operating range, with even sharper throttle response, stronger acceleration and a driving experience worthy of the GLC 63 S, always with a safe and reliable calibration tailored to this specific car.
