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. Many enthusiasts coming from Audi's history of turbocharged vehicles expected massive increases in torque, at lower RPMs, simply by adding an ECU Upgrade. Unlike turbochargers, roots style superchargers are positive displacement meaning they provide a fixed amount of air flow based on engine speed. On the 3.0TFSI Audi chose to use a bypass valve that bleeds off boost pressure when requested. Keeping the valve almost completely shut at lower RPMS allows them to make respectable torque, and, opening the valve at higher RPMs allows them to keep horsepower within their marketing goal. Consequently, the APR Stage I ECU upgrade provides a relatively low increase in torque but an exceptional increase in power. For those demanding more torque, The APR Supercharger Pulley Upgrade is the answer. Spinning the supercharger faster increases air flow and effectively doubles the low-end gains of Stage I. The gain in torque is felt immediately, but the results are present from beginning to end adding up to 80ft-lbs and 108 horsepower at all four wheels!
