APR Tuning’s ECU Upgrades are the best dollar-per-horsepower modification one can make to the Audi/VW 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 installation and setup.

 The APR Stage 1 ECU Upgrade is the first step in gaining impressive power with your vehicle. APR’s ECU upgrades are available in multiple stages and torque levels, supporting various octanes both with or without any hardware or transmission modifications.
