AUDI RS3 8V / TTRS 8S 2.5TFSI EA855 EVO (2018-)  TUNING PACKAGES

The ultimate engine control unit (ECU) upgrade for the 2.5T EA855 EVO (Gen 2) engine!

The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting drive. This is made possible through APR’s optimisation 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.

Optional features, such as APR's EMCS Program Switching and APR Mobile are available.

Each stage includes optimisations to the factory boost gauge making it react more quickly and corrections to the power and torque gauges to match the increased output. Furthermore, you have left foot braking, speed limiter removal, raised rev-limiter and a motorsport limiter, adjusted factory exhaust crackle to protect the catalyst, optimised cold start, retuning of the exhaust flap actuation for the best performance and sound in multiple modes, optimised high altitude mappings, retuning of the throttle for better response, and completely optimised the driving experience for street and track use, making for a much more enjoyable driving experience!

APR Stage 1 - 476 bhp / 470 FT-LBS 

The APR Stage 1 ECU Upgrade is the first step towards making more power!

This simple upgrade requires no engine hardware modifications, and produces 459-542 HP with 451-506 FT-LBS of torque, depending on octane. Gains as high as 66-132 HP and 88-146 FT-LBS of torque are available throughout the power band.

To get more power, the vehicle can be outfitted with an upgraded intake, intercooler, catback exhaust and other small modifications without requiring any new modification to the ECU. Upgrading the small factory intercooler is highly recommended on this platform.

The process will take around 2-3 hours for all engine and gearbox software inc dyno runs.
