LEARN MORE TrueFlex Tuning is included with every stage, additional hardware is required. FULL POWER ON ANY TRANSMISSION 2021+ model years and some 2019-2020 variations are equipped with a Gen 2 factory transmission control unit (TCU) with advanced factory security that locks them from tuning. Stock TCU tunes include software limiters that restrict engine power when torque limits are exceeded from ECU tuning. For A5/A5 models with locked TCUs, our calibration team has custom-coded the engine control unit (ECU) programming to properly manage torque signals to and from the transmission. This advanced strategy safely enables full horsepower and torque, even without a TCU tune. Included on all stages and octanes.   ECU STAGES HIGH-PERFORMANCE ENGINE SOFTWARE B9 2.0T STAGE 1 Add significant increases in performance with up to 359 horsepower and 448ft-lbs from an IE Stage 1 ECU Tune for your Audi B9 A4 or A5.
