This 2007 Chrysler 300C with a 3.0-litre diesel engine and an EDC16CP31 control unit was tested on a dyno in several configurations. The video lists standard figures of 218 hp and 510 Nm.

The car was first measured with an aftermarket tuning box bought online, which uses resistor settings to adjust its output. With the box connected, the dyno recorded approximately 234–235 hp and 582 Nm. After it was disconnected, the original ECU software produced about 228 hp and 532 Nm.

The ECU software was then calibrated, with the emissions systems and EGR retained. With the AutoChip file, the dyno showed approximately 285 hp and 660–661 Nm. The comparison illustrates the difference between an add-on box and changes made directly to the engine control software.
