This BMW E60 with a 3.0-litre diesel engine and two turbochargers had already been tuned at another workshop. It has an automatic transmission, and the turbochargers remained standard. The owner wanted to check the existing result and see whether the calibration could be improved.

With the previous calibration, the dyno recorded approximately 366 hp and 778 Nm. After AutoChip revised the ECU software, the car was tested in fifth gear. The dynamometer recorded 423 hp and 790 Nm.

The video notes that the engine is in good condition and that the turbochargers are not hybrid units. The measurement was made with the existing mechanical setup; no other unconfirmed engine modifications are attributed to the car.
