Audi S4 Performance Tune

Increasing the power and torque output of the Audi S4 enables you to take advantage of the S4's precision, accurate steering and excellent cornering stability.

Simply select your S4 from the drop-down box to find out how much power and torque can added to your Audi S4.

On DSG equipped S4's we are also able to make impressive improvements to shifts including reducing the shift times without sacrificing shift quality, helping to deliver the extra power as quickly as possible.
