This Audi A6 C7 with a 3.0-litre TFSI petrol engine and supercharger received an engine control unit calibration. The car’s nominal output is approximately 300 hp and 420 Nm. Before the software work was completed, the workshop addressed issues related to fuel temperature and sensors.

The Simos 8.5 control unit was removed from the car and programmed on the bench without opening it. The car was then tested on a dynamometer. The video gives a final result of nearly 390 hp and 485 Nm. After calibration, the engine was described as more responsive and stronger under acceleration.

The gain here came from software calibration without replacing the supercharger. Results on another 3.0 TFSI engine will depend on that vehicle’s condition and measured output.
