This 2006 BMW E61 with a 3.0-litre diesel engine was prepared for a power increase. The video notes that the DPF, EGR and some intake components had already been modified or removed, while the turbocharger, injectors and other major engine parts remained standard.

Before the new software calibration, the dynamometer showed 233 hp and 511 Nm. The initial Stage 1 calibration produced 270 hp and 624 Nm, but the owner wanted more power. After further adjustment, the video gives a final result of 291 hp and 705 Nm.

This example shows how dyno measurements can be used to compare an intermediate result with the final one. The figures apply to this vehicle’s specific configuration, including its existing hardware changes.
