Are you looking for more power, torque or a substantial increase in performance from your S6?

The Twin Turbo 4.0TFSi in the C7 S6 (as well as the C7 S7) has a HUGE potential which can be unlocked with an upgrade such as the APR Stage 1 ECU remap. Through optimising fuelling, ignition, boost and many other maps inside the ECU a substantial improvement in power, torque and driveability can be enjoyed. If you want to take it a step further, the RS6/RS7 turbos can also be installed for an even higher performance improvement!
