The Audi 3.0T turbocharged V6 found in newer S4 and S5 platforms delivers impressive factory performance and responds exceptionally well to ECU calibration. TuneZilla’s tuning optimizes boost control, ignition timing, fueling, and torque management to safely unlock substantial gains in horsepower and torque while maintaining OEM-like drivability.
Our calibrations improve turbo response, increase mid-range power, and deliver a significantly more responsive driving experience throughout the entire rev range.
Stage 1 is designed for stock hardware vehicles running premium fuel ( 93 ) and delivers major gains in both power and torque.
Neutral/Park rev limiter raised
Road speed limiter removed
Brake boost enabled for rolling launches
Auto start/stop updated with memory on last position
Improved throttle response
Faster turbo response
Stronger mid-range acceleration
OEM-like drivability with significantly improved performance
93 Octane (98 RON)
This platform must be tuned through an authorized TuneZilla dealer.
For best results, we recommend using either:
CMD Loaner Tool
Autotuner via OBD
2021+ vehicles require TCU unlock when using Autotuner
Proper maintenance is strongly recommended prior to tuning
Spark plugs should be inspected and replaced if necessary before flashing
Stage 2 further increases performance through optimized calibration designed for upgraded hardware setups
Crackles
Massive gains in torque and acceleration
Improved turbocharger efficiency and response
Stronger top-end power delivery
Enhanced overall drivability and responsiveness
Performance intake
Upgraded intercooler
Performance downpipe
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.
Increased clutch pressure
Optimized shift speed and response
Raised torque limiters
Improved launch control behavior
Faster paddle response
Enhanced shift strategy in automatic and manual modes
Optimized gear holding under acceleration
Improved drivability during spirited driving
This TCU tune is compatible with vehicles equipped with the:
AL552 transmission
Bosch MG1CS002 ECU
B9 S4/S5/SQ5
B9 RS4/RS5,
C8 RS6/RS7/Q7/Q8/SQ8/SQ7/SQ8/A6
Urus
2021+ vehicles require TCU unlock with Autotuner. Please open a ticket for further support.
