Audi S6 Tuning Box Kit Improves Horsepower on the 4.0L Twin Turbo VRTuned.com May 16, 2016 Product Info Audi’s 4.0L twin turbocharged engine that is found in the new S6 is a menacing beast with 420bhp stock. Audi S6 Tuning can yield some very impressive gains via a ECU flash or tuning box. For those looking to add some no hassle, warranty safe power, the VR Tuned Tuning Box is the way to go. Plugging into factory sensors, the Tuning Box takes the Audi S6 4.0L to 540bhp and 700nm of torque! Thats quite the difference! You can see the dyno graph of our test car we did here at Vivid Racing. The tuning box has a dial on it which can be adjusted up or down for different octane used. As seen here, the dial is set to 5/6 for 93 octane cars and for 91 octane, we recommend 3/4 setting. This tuning box harness fits the other 4.0L twin turbo engines such as the Audi A8, S7, and more.
