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
Stage 1 Plus is included at no additional cost.
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.
While no hardware upgrades are required for Stage 1, upgrading the intake, turbo inlet, and intercooler will provide increased airflow, lower intake air temps, and quicker heatsoak recovery for an overall more efficient and faster vehicle.

IE ECU tunes far exceed the torque limitations of the stock RS5/RS4 transmission programming, which triggers the TCU to limit power output. The included IE stage 1 TCU tune raises these torque limits while keeping all transmission driving characteristics otherwise stock.
Stage 1 TCU is included with all ECU tunes at no extra charge.
IE's Stage 2 and 2 Plus TCU tunes are complete performance transmission calibrations that delivers lightening fast shifts, optimized shift points, multiple launch-control modes, enthusiast drive mapping, and more! Pairing this TCU calibration with an IE Stage 1 or Stage 2 ECU tune will significantly transform every aspect of your RS5 or RS4, delivering faster launches, higher Gs, and further improved acceleration. Stage 2 Plus TCU is for use with Stage 1 & 2 Plus ECU tune.
Stage 2 & 2 Plus TCU is an optional upgrade and sold separately.
Stage 2 TCU remaps each gear's RPM limits for the fastest possible acceleration by shifting at the optimal points to keep the engine in peak torque/power output. This strategy pulls the car through the powerband as quickly as possible with incredible improvements in acceleration and G's. These optimized shift points occur when in drive mode, sport mode, and AMAX. The transmission limit remains 7000 RPM in all gears in manual mode, retaining complete manual control over the shift points.
