This 2000 BMW E46 2.0D with an EDC16C31 control unit came in for ECU calibration and a power increase. The EGR valve had already been removed or disconnected, and the owner wanted the ECU software adjusted to match.

Before calibration, the dyno recorded 154 hp and 356 Nm with the original ECU file. After the software was revised, the final result was approximately 191 hp and 447 Nm.

The technician noted that further power gains might require improvements to the engine's air supply, including a larger intercooler. These were described as possible next steps, not as completed work.
