APR is pleased to present the world’s first Supercharger Pulley and corresponding ECU Upgrade for the Audi C6 A6 3.0 TFSI. Without recalibrating the ECU found in Audi’s latest line of supercharged direct injected vehicles, pulley upgrades offer no advantage, as the supercharger will simply bypass boost pressure. With APR’s ability to expertly recalibrate the 3.0 TFSI Engine Control Unit, we are able to develop new hardware and calibrate the ECU to work properly as if intended by the factory.

The gain in torque is felt immediately, but the results are present from beginning to end adding up to 90ft-lbs and 113 horsepower at all four wheels! Read More
