The factory figures for this 2017 Ford Focus with a 1.5-litre diesel engine are 120 hp and 250 Nm. Before the software was changed, the dynamometer showed 125 hp and 214 Nm.

The owner chose a Stage 1 power increase while keeping the DPF, catalytic converter and the rest of the emissions equipment in place. The EDC17C70 engine control unit was diagnosed and reprogrammed through the OBD connection, without removing it from the car.

The video describes writing the program and the intended Stage 1 adjustment, but it does not provide a reliably identifiable final dyno reading after calibration. For that reason, no unverified power or torque increase is stated here.
