Notes
Disclaimer
Proper vehicle maintenance is essential before tuning. Ensure the engine, turbos, and ignition system are in good condition. Neglecting maintenance or tuning a vehicle with existing mechanical issues can result in reduced reliability or unsafe operation.
⚠️ Note: Stage 1provides substantial increases in performance. This can place additional stress on driveline components during aggressive driving. Supporting modifications and proper maintenance are recommended for long-term reliability.
Audi AL552 TCU Tune
The Audi AL552 transmission is capable of handling substantial performance increases, but factory calibration can limit the full potential of the drivetrain. TuneZilla’s TCU calibration is engineered to optimize shift strategy, clutch pressure, torque limits, and launch behavior to deliver faster, smoother, and more consistent performance.
Our AL552 TCU tune is designed to work seamlessly alongside TuneZilla ECU calibrations for the 2.9T platform, improving drivability while allowing the transmission to properly manage increased torque output.
