This SEAT Altea 2.0 TDI with a PPD1.x ECU initially produced 150 hp and 335 Nm on the dyno. The video compares those readings with the quoted engine figures of 170 hp and 350 Nm. The goal was therefore not only to increase power, but also to check how the vehicle was operating.

Inspection showed that the DPF had already been removed; weld marks were visible on the exhaust system. After ECU calibration, the dyno recorded approximately 190 hp and 415 Nm. Road and dyno checks included logging turbocharger, injector, fuel-delivery, airflow-meter, and EGR data.

The video does not confirm a single cause for the initial output shortfall. It states that the collected logs would be analysed and the findings explained to the owner. No significant visible smoke was reported during the final check.
