Audi S4 Performance Tune

Audi promotes the S4 with the promise of "Power meets precision," highlighting its balance of performance and handling. In factory form, the precision is already there. The power simply hadn’t been properly introduced yet. That’s where AutoUpgrades comes in. Our Audi S4 ECU tuning delivers the additional performance required to fully realise that balance.

Key Features:

Enhanced Power: Substantial increases in horsepower and torque across multiple Audi S4 variants through precise ECU calibration.
Improved Driving Dynamics: Enhanced mid-range torque and throttle response for stronger acceleration and improved real-world performance.
DSG Transmission Tuning (where fitted): Improved shift speed, clutch control, and torque delivery for DSG-equipped S4 models.
ZF 8HP Transmission Tuning (where fitted): Optimised shift strategy, improved responsiveness, and refined torque management for longitudinal S4 variants.

Power Gains:

1997–2002 S4: +50HP, +100Nm
2003–2004 S4: +28HP, +40Nm
2004–2008 S4: +20HP, +30Nm
2008–2015 S4: +45HP, +90Nm
