APR’s ECU Upgrades are available in multiple stages, supporting various octanes both with or without any hardware modifications. All stages are fully compatible with an upgraded intake, cooling system, catback exhaust, or other minor bolt on modifications. APR Stage II software is available for a high flow Race DP exhaust system and Stage III software is available for use with upgraded RS6 and RS7 turbos.

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!
