The owner of this 2018 Opel Insignia 2.0D came to AutoChip because the car felt sluggish and lacked response when overtaking. The visit focused on improving engine performance and measuring the result, not on repairing the AdBlue system. Its SCR/AdBlue software had already been changed at another workshop.

Before calibration, the dyno recorded 162 hp and 354 Nm, compared with factory figures of approximately 170 hp and 400 Nm. A file supplied by the other workshop did not match the software installed in the vehicle’s ECU, so it was not written to the car. After inspection and ECU calibration, the dyno result was approximately 181–182 hp and 419–420 Nm.

The DPF and EGR remained installed; this visit focused on engine power and response. The increase was checked on the dyno, but the video does not identify a specific mechanical cause for the earlier output shortfall.
