Overview
Unlock the performance potential of your Audi B9/B9.5 RS5 2.9T V6 twin-turbo with the Integrated Engineering (IE) ECU Tune Suite. Designed to take advantage of the 2.9T platform's performance headroom, IE tuning delivers up to 522 HP on pump gas and up to 604 HP with ethanol, depending on the selected software, fuel, and vehicle configuration.
Choose from three software suites — Core, Pro, and Apex — to match your performance goals. Every suite includes POWERlink Mobile flashing, AutoProtect safety logic, Stage 1 maps, 91 and 93 octane maps, and lifetime support. Upgrade to Pro for Stage 2 maps, TrueFlex ethanol support, and additional vehicle controls, or choose Apex for advanced launch strategies, rolling anti-lag, boost-by-gear, and adjustable throttle response.
With POWERlink Mobile, you can flash and manage your tune from a compatible phone. Supported live controls are accessible through the app or CarPlay, allowing you to adjust available features without reflashing the ECU or installing separate control hardware.
