This Audi A5 with a 3.0-litre diesel engine and quattro all-wheel drive came in for a Stage 1 remap. The initial dyno test showed 282.8 hp and 632.9 Nm. The figures supplied by the owner were close to the measured result.

The ECU calibration was adjusted while retaining the exhaust after-treatment hardware. After the work, the dyno showed about 335 hp; the video gives approximately 740 Nm as the torque result. The repeat runs varied slightly, which the video attributes to rising temperatures.

After programming, the car was checked on the road and tested again on the dyno. The video shows results for this particular vehicle; they do not guarantee the same figures for another Audi A5.
