The owner of this BMW 320d with a 2.0-litre diesel engine wanted more power while keeping the engine’s mechanical setup standard. Before the software was changed, the dynamometer showed 160 hp and 344 Nm.

After the engine control unit was recalibrated, we measured the car again. The result was 214 hp and 447 Nm. The readings provide a direct comparison of power and torque before and after the adjustment.

The outcome depends on the condition and configuration of each vehicle. In this case, the video shows the difference between the initial dyno reading and the result after the software change.
