This 2008 BMW E91 came in for DPF and EGR system work and a power check. After the initial measurement, the car was prepared for an engine control software change; the video describes disabling the DPF and EGR in software.

The video title gives a factory power figure of 197 hp and a final result of 262 hp and 586 Nm, along with an increase of 42 hp and 117 Nm. The spoken initial dyno reading is about 220 hp and 469 Nm, so the different groups of figures refer to different comparison points.

A dynamometer helps assess the car’s actual output after a software change, but comparisons should distinguish factory ratings from the specific starting dyno measurement.
