This 2009 Audi A6 3.0 TDI with an EDC17CP14 ECU and manual gearbox was tested on a dyno. The emissions-system and intake configuration had already been changed before calibration. Its initial reading of 247 hp and 485 Nm is therefore not a direct comparison with factory figures for a fully standard car: 240 hp and 500 Nm.

Software development and repeat testing

The first calibration produced about 296 hp and 560 Nm. The software was revised, and the next run showed 305 hp and 655 Nm. A repeat check produced approximately 303 hp and 652 Nm; the small differences were attributed to engine heat and test conditions.

The video shows several consecutive runs rather than relying on one peak result. Dyno readings were also considered alongside engine temperature and other test conditions.
