This 2005 BMW E46 with a 3.0-litre diesel engine had already received an earlier calibration. During the initial tuning stage, the dynamometer showed 267 hp and 621 Nm; further software adjustments were then planned to improve the result.

The video title gives a final result of 299 hp and 655 Nm. This is separate from the earlier reading, so it should not be confused with the initial 267 hp and 621 Nm measurement.

Dyno testing makes it possible to track each stage of calibration and compare the final result with the previous setup.
