  • APR ECU Upgrade for the Audi RS6/RS7 4.0 TFSI V8

    APR ECU Upgrade for the Audi RS6/RS7 4.0 TFSI V8

    APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to the 4.0T engine. The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. This is made possible through APR’s optimization of the factory engine management system to take full advantage of the engine’s capabilities, without needing any end user adjustment. The software loads to the factory ECU through the OBD-II port, resulting in a clean and headache-free install. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!
