This Volvo S60 with a 2.0 D3 diesel engine was brought in for a power increase without changes to its emissions systems. The DPF and EGR remained in the vehicle’s original configuration.

Before the software change, the dynamometer showed 147 hp and 355 Nm. After the engine control unit was recalibrated, the video gives a result of 190 hp and 424 Nm. Compared with the factory figures of 136 hp and 350 Nm, that is a difference of 54 hp and 74 Nm.

Measurements before and after calibration help compare the actual result rather than relying only on nominal factory figures. All values apply to this Volvo and its condition.
