Stage 2 Performance Engine Tune for 2.5 TFSI EVO

The Unitronic Stage 2 ECU Performance Engine Tune is a precision-engineered software calibration designed to maximize the power output of the Audi 2.5 TFSI EVO engine. By optimizing power delivery across the entire power band, this software provides significant increases in horsepower and torque when paired with full hardware bolt-ons. Key features include an enabled exhaust crackle/overrun, removal of the speed governor, and enabled left foot braking capabilities. Installation of this performance software requires the use of the UniCONNECT+ interface, which allows for convenient flashing from your own garage. To ensure a stable, uninterrupted installation process, the use of a battery charger is recommended. This system also enables the user to quickly revert the ECU back to factory stock calibration if necessary. Required hardware for this Stage 2 tune includes the Unitronic 2.5TFSI EVO spark plug set (NGK R7437-9), an upgraded 3 or 4-inch intake system, a matching 3 or 4-inch turbo inlet elbow, a high-flow downpipe with midpipes, and an upgraded intercooler. Additionally, the Unitronic Stage 2 TCU Performance Software is strictly required to run this ECU tune. Fitment is specific to 2018-2021 Audi TTRS 2.5 TFSI EVO and 2017-2019 Audi RS3 2.5 TFSI EVO models. For 2019 and newer models, the hood may need to remain open during the flashing process.
