APR Plus ECU Upgrade - 2.9T EA839 V6 (B9 RS5)

The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. The software is installed to the vehicle's factory ECU through the OBD-II port once the ECU is unlocked, resulting in a clean and headache-free install. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!

The APR Plus ECU Upgrade is the first step towards making more power, and it includes our limited powertrain warranty. This simple upgrade requires no engine hardware modifications, and produces 488 HP with 537 FT-LBS of torque. Gains as high as 75 HP and 89 FT-LBS of torque are available throughout the power band, making the vehicle exceptionally quicker in all scenarios.

The APR Plus ECU Upgrade matches the performance of our Stage 1 ECU Upgrade (91 octane). To get even more power, you can add any of our other Stage 1 compatible products and still be covered under the APR Plus warranty!
