APR’s RS6/7 Turbo ECU Upgrade for the C7 S6/7 4.0 TFSI

engineAPR’s RS6/7 Turbo ECU Upgrade is now available for the S6/7 4.0 TFSI!

APR’s RS6/7 Turbo ECU Upgrade is designed for use with Audi’s high output RS6/7 4.0 TFSI turbochargers, which are a direct bolt on to the factory S6/7 4.0 TFSI Engine. This upgrade offers 634 HP and 671 FT-LBS of torque on 93 octane fuel and 707 HP and 714 FT-LBS of torque with race fuel! The substantial increase in power and torque comes with lightning fast response and smooth daily driving that transforms the vehicle into a new class of enjoyment!

Working closely with our partners at NGP, who supplied the original test vehicle and offer the necessary hardware, APR’s Calibration Experts recalibrated the factory Bosch MED 17 engine management system to work seamlessly with the upgraded turbochargers, and offer a range of flexibility depending on vehicle modifications. Though the upgrade works well with with factory charge cooling, the ECU Upgrade is calibrated to take advantage of any cooling upgrades that are made. Additionally, the upgrade will work with the factory downpipes, though output will be less than advertised.

APR’s RS6/7 Turbo ECU Upgrade comes with all the benefits and features, including APR EMCS Program Switching and APR Mobile, as found on APR’s Stage I and II ECU Upgrades, and is conveniently flashed through the vehicle’s OBD-II port.
