This is RacingLine's OEM+ performance ECU software for the 2017-on Audi RS4 and RS5 B9 / B9.5 with the 450 PS DECA 2.9 TFSI twin-turbo V6. Developed on road, track and dyno, the calibration transforms the EA839 while keeping progressive, factory-like response. Choose Stage 1 with no hardware changes, or Stage 2 for eligible non-OPF cars with supporting airflow and catalyst upgrades. TCU software is strongly recommended to unlock the full calibration and optimise the AL552 gearbox.
