APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to their turbocharged engine. The upgrades dramatically increase horsepower and torque, making for an exceptionally quick 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. The software loads to the factory ECU through the OBD-II port, resulting in a clean and headache-free install.

APR ECU Upgrade Stages

APR’s ECU Upgrades are available in multiple stages and torque levels, supporting various octanes with or without any hardware or transmission modifications. Specific software is available for use with a high flow downpipe exhaust system, while all stages are fully compatible with an upgraded intake, intercooler, catback exhaust, or other minor bolt-on modifications. Finally, each stage is offered with special “Low Torque” software, designed to limit peak torque for use with an unmodified factory manual clutch, or DSG transmission.
