This 2003 Mercedes-Benz E 320 CDI arrived at AutoChip with approximately 471,000 km on the odometer. Before calibration, the dyno produced around 210 hp and 529 Nm. The exhaust configuration had been changed, and the video also shows ECU calibration work and changes to EGR control.

Data checks and results

The video gives post-calibration figures of about 250 hp and 608 Nm. The data log showed that, at high load, measured air supply did not reach the requested value, and temperatures rose. For anyone considering a further power increase, a larger intercooler was recommended. It was not fitted during this job.

The car was retested on the dyno and checked on the road. The result should be considered in the context of this vehicle’s condition, high mileage and installed hardware.
