APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.5T engine!

-415-435HP

APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to the 2.5T engine. The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. This is made possibly 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.

The APR Stage 1 ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications, and produces 415-435HP with 588-630NM of torque depending on fuel grade. Gains as high as 61-86HP and 95-136NM of torque  are available throughout the power band, making the vehicle exceptionally quicker in all scenarios.
