This 2012 Audi A6 C7 3.0 TDI already had a hybrid turbocharger and a larger intercooler fitted. The video also describes changes to the exhaust and emissions-system configuration. Before the final engine calibration, a dyno run with the previous software produced about 261 hp and 535 Nm.

Calibration and dyno results

After the engine control unit was calibrated, the result was approximately 350–355 hp and around 700 Nm. The video shows slightly different readings on separate runs, so the result is best treated as an approximate range rather than one fixed figure. A larger turbo can build boost later than a smaller one, which may change response at lower engine speeds.

The automatic transmission software was also recalibrated to account for the engine torque. Engine operating limits were retained, and the outcome depends on the hardware configuration of the individual car.
