An Audi A7 3.0 TDI, whose owner had travelled from Estonia, was checked on the AutoChip dynamometer. Before calibration, the engine control software was read through OBD and on the bench to confirm that the car had its original file. Data logs were used to check the turbocharger, fuel system and other engine parameters.

After the Stage 1 software was installed and the car was tested on the dyno, the result was 313 hp and nearly 650 Nm. The video reports an increase of about 60 hp and 120 Nm. The DPF, EGR and intake flaps remained in the vehicle configuration; the recording does not say that these systems were removed or disabled.

DPF condition after the measurement

Data logs showed DPF backpressure of approximately 400 mbar under high load and above 4,000 rpm. The technician said the filter was not in perfect condition and might need regeneration. He suggested that power could improve somewhat after regeneration, but the video does not confirm that regeneration was carried out or show its result.
