This Audi A4 1.8T had been extensively modified with a TurboWorks turbocharger, a larger intercooler, Bosch injectors, and an upgraded fuel pump. It already had an earlier aftermarket calibration, but the owner described uneven running. The airflow meter was also checked; a unit from a higher-powered Audi TT version was fitted, after which engine operation improved.

AutoChip calibrated the engine ECU for the installed hardware and checked the result on a dyno. The main run recorded 276 hp and 440 Nm. Compared with the factory figures quoted in the video—190 hp and 240 Nm—this is a substantial increase, although the original setup before the earlier modifications was not measured on this dyno.

The engine warmed up during repeated dyno runs, which may have affected the readings. The owner also said they planned to remove the LPG equipment later; the video does not confirm that this work had been completed.
