Stage 1 IE Performance ECU Tune - Includes Stage 1 TCU Tune & POWERlink Cable

With a Windows laptop computer, unleash your engine's potential while maintaining factory reliability and comfort. IE's motorsport-inspired software brings track-ready ECU programming to your vehicle while retaining factory comfort and reliability. Developed in-house, IE engineers are equipped with industry-leading tuning technology to completely reverse engineer the factory mapping and safely modify it to maximize performance. Years of professional tuning high-powered race vehicles and intimate knowledge of the VW & Audi engines results in a wicked fast car on the street or the track. Your new software tune is easily uploaded to your factory installed ECU (engine control module) without touching a wrench in your own driveway. Multiple tunes are available to match your stock or installed aftermarket hardware.

IE Stage 1 ECU calibration is a simple flash-only upgrade that delivers instant performance with up to 542HP and 558ft-lbs of torque! The larger powerband, 7000RPM rev limit, and increased boost pressures produce exceptionally faster 0-60 times and acceleration in any scenario. This advanced calibration can be installed in an entirely stock car or will adapt to take advantage of intake and intercooler upgrades.

IE Stage 1 Plus delivers the most power possible from E85 fuel with an upgraded HPFP (High Pressure Fuel Pump). By increasing the fuel pump's ability to supply additional ethanol demands, our Stage 1 Plus tune produces an even more significant surge in power with a massive 604 horsepower and 660ft-lbs of torque! This ECU calibration pushes your Audi RS5/RS4 into a higher vehicle class of performance with an intense pull. Requires HPFP upgraded internals with 11.7mm pin size.

• Enables launch control in drive, sport, and manual modes
• Includes user-adjustable launch control
• Lightning-fast shift speed
• Optimized shift points for the fastest acceleration
• Enables 7000 RPM limit in all gears in manual
• 7th and 8th gear enabled in sport mode
• Enables downshifting into 1st gear without coming to full stop
• Refined drive for the automotive enthusiast
• Reduces time for double-downshifting gears
• Line pressure increased to protect against trans slip
