This C7 S6 is back to Excelerate Performance for some upgrades from our friends at APR and AWE Tuning.
First up: APR’s v1.1 software revision update. With new found power and torque and a huge gain in driveability, we recommend all current stage 1 C7 4.0T customers visit their APR dealer to get updated. Secondly, an AWE Tuning S-Flow Carbon Fiber Intake is installed by #teamexcelerate.
These twin turbo V8’s run very well in factory form and even better tuned. Turbos require a plethora of fresh cool air to supply them. The factory intake is a large restriction once you start making more power, removing the restriction on the inlet side allows the turbos to operate and deliver its power more efficiently.
