Baseline dyno measurement

A VW Tiguan with a 2.0-litre diesel engine, 4Motion all-wheel drive and an automatic transmission was tested on a dynamometer. The factory nominal figures mentioned in the video are 140 hp and 320 Nm; the initial dyno run recorded 131 hp and 308 Nm.

Stage 1 calibration

A Stage 1 software calibration was prepared for the engine control unit. The vehicle’s emissions-control equipment was left in place. After the changes, the Tiguan was tested on the dyno again.

Results after calibration

The follow-up measurement showed 165 hp and 413 Nm. Compared with the initial dyno result, that is an increase of 34 hp and 105 Nm. The graph shows both the original and modified power curves, with higher torque after the Stage 1 calibration.

The power and torque results for this vehicle were checked on the dynamometer. The comparison shows the change recorded on this Tiguan, with its emissions-control equipment left in place.
