This 2007 BMW X3 3.0d came in for a power check and engine ECU remapping. Before the visit, the owner had removed the DPF and EGR system hardware. The initial dyno run produced 183 hp and 365 Nm, and diagnostics also showed faults related to the exhaust system.

After the ECU was remapped, the vehicle was tested again on the dyno. The readings shown near the end of the video were approximately 259–260 hp and 520–523 Nm. The repeat runs produced similar results.

These figures describe this particular vehicle and test. The engine’s condition and the vehicle’s configuration should be considered before choosing a similar calibration.
