APR 2020+ Audi S8 (D5) 4.0 TFSI (EA825) ECU Upgrades!

[Arin@APR]

Details

We're excited to announce our Engine Control Unit (ECU) Upgrades are now available for the Audi S8 (D5) 4.0 TFSI V8 engine with the Bosch MG1 ECU! Expect massive gains with up to 685-767 HP and 731-804 FT-LBS of torque on tap, depending on octane, from this simple software upgrade.

APR's ECU Upgrades are the best dollar-per-horsepower modification one can make to improve engine performance. 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 ECU Upgrades are available with various features and supported octane levels and each stage is compatible with most typical bolt-on modifications. 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!
