Experience the supercar-crushing performance of iE Stage 3 engine and transmission tunng designed for the bolt-in PURE800 twin turbo upgrades. Your RS5 will be completely transformed into a torque-rich powerhouse with explosive throttle response, minimal lag, and relentless pull through redline. Experience massive horsepower gains while preserving the everyday comfort and refinement.
IE's 2.9T ECU upgrade dramatically increases horsepower, torque, engine response, power delivery, and more to release the full performance potential from your 2018-2023 Audi RS5 or RS4! Multiple stages are available to match typical bolt-ons and offer various fuel options and features while maintaining stock comfort and reliability. Enjoy a hassle-free install in minutes through the vehicle's OBD-II port, and get ready for supercar power from your RS-class Audi!
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
IE Stage 2 and Stage 2 Plus ECU tunes are calibrated for aftermarket downpipes to deliver a louder exhaust note and include a more aggressive exhaust overrun/crackle feature in dynamic drive mode. The 2.9T engine includes two already efficient factory downpipes that do not result in power or exhaust restrictions on stock turbocharger ECU tunes. Although this platform does not provide additional power gains on Stage 2 tunes, IE files will provide the necessary ECU calibrations to support aftermarket downpipes for users looking for a more aggressive exhaust note.
Upgrading from Stage 1 to Stage 2 or beyond is easy! With IE, you only pay the difference in tune cost with no extra fees. After installing any required hardware, launch your IE POWERlink software and enjoy the next power level in minutes!
