Audi S5 Sportback B9: Stage 1 + TCU, 420bhp & 647Nm

This Audi S5 Sportback (B9) came in for our Stage 1 custom dyno tune for its 3.0 TFSI V6, with a TCU calibration for its 8-speed tiptronic gearbox, both developed on the same visit.

The numbers

On the baseline run it made 347.8bhp and 546Nm. With our calibration and the TCU calibration it made 420.2bhp and 647Nm, with 355.2bhp at the wheels. That is 72.4bhp and 101Nm more:

More torque than a B9 RS5

Audi’s own B9 RS5 makes 600Nm. Standard, this S5’s torque dips to around 450Nm at 2,800rpm; tuned, it makes over 610Nm there. It holds over 600Nm from around 2,700 to 4,100rpm, with 100Nm or more extra torque from around 2,600 to 5,400rpm and 70bhp or more extra power from around 3,700rpm to the top of the stock run.

The gearbox, tuned with the engine

The 8-speed tiptronic’s TCU was calibrated on the same visit, set up to match the extra torque, so the engine and gearbox are calibrated as one package instead of two separate jobs.

How it was done

Diagnostics and a health check first, then baseline runs on our 4WD linked dyno with live data logging. The engine calibration was built from there with repeated runs, the gearbox calibration was set up to match, and the final pulls verified the result. No generic files: a calibration written for this car, proven on our dyno.
