Preparing the car

This 2009 Audi S4 B8, powered by a 3.0-litre V6 TFSI engine, had previously visited the workshop for an assessment of its condition. After the issues identified at that time had been addressed, the car was checked again and considered suitable for Stage 1 calibration. The catalytic converters and other standard equipment remained in place.

Baseline measurement and Stage 1

Before calibration, the dyno recorded 308 hp and 400 Nm. The factory nominal power figure mentioned in the video is 333 hp. After the engine ECU software was calibrated, the dyno showed 378 hp and 486 Nm.

Result

Comparing the two dyno runs gives an increase of 70 hp and 86 Nm. Power rose by 70 hp, while the torque gain was close to 90 Nm. The result was checked on the dyno, and the video shows the original and modified power curves.
