IE Stage 2 ECU Performance Engine Tune For B9 Audi RS4/RS5 2.9T

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 2.9T Stage 2 / Stage 2 Plus

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.

Maximized Output

IE's advanced tuning technology suite allows our software engineers to realign all safety protocols and sensors for the new performance calibration. Every tune parameter undergoes months of testing on our in-house dyno systems that utilize the world's only Sea Level Generator developed specifically to verify tune operations in any condition. Confidently drive from LA to Pikes Peak with the power to keep you smiling every mile!
