The owner of this 2014 Mercedes-Benz Sprinter with a 2.2-litre diesel engine wanted to improve its performance. Before changing the software, we measured the van on a dynamometer: it produced 129.3 hp and 322 Nm.

After the engine control unit was recalibrated, we tested the Sprinter again. The video gives a result of approximately 185–186 hp and 465–466 Nm. Compared with the initial measurement, that is about 55–56 hp and 143–144 Nm more.

A dynamometer test shows not only peak power but also how the engine delivers torque. These figures apply to this particular vehicle and its condition.
