The owner of this Audi A4 2.0 TDI wanted a previous remap, carried out elsewhere, checked because the car still felt underpowered. The factory figures are approximately 140 hp and 340 Nm. With the previous file, the dyno produced only about 95 hp and 260 Nm. Testing with the factory software gave around 94 hp and 260 Nm, so the previous file had added very little.

AutoChip prepared a different calibration. The dyno then recorded about 128 hp and 340 Nm. However, the turbocharger reached full boost too late, limiting the output available at the time. The turbo had previously been rebuilt and adjusted, but further mechanical inspection and adjustment were still recommended.

The particulate filter remained fitted, and no pronounced smoke was observed during testing. These dyno figures reflect the engine’s condition during the visit; any further potential depended on correcting the turbocharger response, which had not yet been confirmed.
