This 2012 Audi A6 C7 has a 3.0-litre TFSI petrol engine with a supercharger and a Simos 8.5 control unit. Factory output is approximately 300 hp and 420 Nm. Issues related to fuel temperature and sensors were identified in the engine control system and addressed before the calibration was completed.

The control unit was removed 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. This is the result for this particular car, not a guaranteed gain for every 3.0 TFSI engine.

This example shows that a supercharged petrol engine can also be calibrated. An atmospheric engine without a supercharger or turbocharger generally gains much less from software changes alone, so the engine type and a realistic target should be considered before tuning.
