This Mercedes-Benz C-Class with a 2.1-litre diesel engine and a CRD3.10 control unit came in for power calibration. The video lists original figures of 170 hp and 400 Nm. The owner requested more power and a change to EGR control, while keeping the DPF fitted to the vehicle.

Before the power calibration, after changes to the emissions system, the dyno recorded 225 hp and 458 Nm. The final test after Stage 1 calibration produced approximately 214 hp and 520 Nm.

The video shows measurements from different stages of the work, so the intermediate result of 225 hp and 458 Nm should not be confused with the final result after ECU calibration. The DPF was retained.
