This BMW E46 Touring has a 2.0-litre diesel engine and an EDC16C31 control unit. It was tested on the dyno before and after the engine software was changed. The video gives factory figures of 150 hp and 330 Nm; the initial dyno reading was 148 hp and 380 Nm.

The catalytic converter was already absent, but the ECU had not previously been tuned. The engine calibration was adjusted after the initial run. The power test was performed with the automatic transmission in fifth gear.

After programming, the dyno recorded about 188 hp and 470 Nm. The increase should be assessed against this car's initial dyno reading, not only its factory specification.
