The owner of this Audi A6 C6 3.0 TDI wanted to check work previously carried out elsewhere and improve the car’s performance. The initial dyno run with the installed software recorded 222 hp and 452 Nm. After reading and checking the file, no power increase was found in it, despite the owner having been told that the car was already tuned.

After ECU calibration, the dyno recorded 280 hp and approximately 565 Nm. A later test run showed around 570 Nm, so the readings varied slightly between runs. Compared with the initial dyno measurement, the increase was approximately 58 hp and 113–118 Nm.

The car has an automatic transmission. A road test followed the dyno check. The customer received a warranty for the work and a dyno printout documenting the result.
