+112HP & 95lbfts APR Stage 1 ECU + TCU B8.5 S5 Upgrade

How does 440HP+ sound from your B8.5 S4? This customer got just that, with an APR Stage 1 ECU & TCU Upgrade.

BIG gains are available on the supercharged 3.0TFSi equipped B8/B8.5 S4 and S5 models. APR's Stage 1 ECU software optimises the fuelling, ignition and many other maps inside the ECU to improve power, torque and driveability.

The TCU/DSG software then optimises the DSG software for ultra-fast shifting and most importantly, a higher rev limit which allows the supercharge to complete more revolutions, producing more boost, resulting in higher horsepower figures vs. the Stage 1 ECU software alone.

The horsepower and torque can further be improved with the addition of either the or a combination of supercharger pulley, crank pulley, ultra charger and charge cooler heat exchanger upgrade.

🔵 Baseline = 336HP & 338lbfts
🔵 Max Gains = +112HP & 95lbfts
🔵 Peak Gains = +110HP & 49lbfts
🔵 Maximum Output = 446HP & 387lbfts
