This Alfa Romeo 166 with a 2.4 JTD engine arrived at AutoChip after a recent major rebuild. It already had an ECU calibration, and the initial dynamometer run recorded 172 hp and 313 Nm. This reading described the car in its current condition, rather than its factory output.

After the initial measurement, the engine power calibration and EGR control settings were adjusted. Since the engine had recently been rebuilt, the readings needed to be considered in the context of its current mechanical condition.

After programming, the car was tested on the dynamometer in fourth gear with the automatic transmission. The video shows the test and the car's response, but no exact final power figure is given because the results in the title and narration differ.
