The 2010 Opel Insignia with a 2.0 CDTI engine returned to AutoChip about a month and a half after earlier changes had been made to its DPF and EGR systems. The initial dyno test recorded 142 hp and 327 Nm.

Given the owner’s preference for a moderate increase and the video’s mention of concerns about the engine’s connecting-rod bearings, the calibration was kept restrained rather than aiming for maximum torque. After the software adjustment, the dyno recorded 161 hp and 356 Nm.

No black smoke was observed during the test, according to the video, and the car was described as driving well after calibration. These are dyno results for this particular Insignia; they do not verify the condition of the engine bearings or its future service life.
