HIGH PERFORMANCE ENGINE PROGRAMMING
IE 2.9T STAGE 1
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.
See performance tab for full performance results & dyno reports
IE 2.9T STAGE 1 PLUS
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 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.
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. When you install the required matching hardware, follow the instructions on your IE POWERlink app to purchase the tune upgrade, and you will be blowing away the competition in minutes!
HARDWARE GUIDE
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.

TECHNICAL FEATURES
IE calibration engineers have not only made the engine more powerful, every ECU stage includes extensive adjustments and features to make every bit of the driving experience refined and enjoyable.
BRAKE BOOST
Brake Boosting is commonly used in roll racing, which allows you to build extra boost by applying brake pressure while accelerating. Release the brake pressure for a "rolling launch" or extra power surge.
Brake Boost is included on all tune stages.
EXHAUST OVERRUN
Stage 2 files turn up the volume on exhaust overrun crackles for an exciting exhaust sound on engine decel and when free-revving in neutral or park. This feature is only enabled in Dynamic drive mode. Exhaust Overrun is included on stage 2 tunes only.
BOOST CONTROL
The stock ECU, boost control programming is a very "close enough" approach, which works fine in low-boost and stock power output. When increasing performance, this slow response is reflected in the torque curve and can feel erratic on long power pulls. IE calibrators have smoothed the power curve by introducing a new boost control mapping strategy with precision boost request targeting, resulting in unmatched power delivery.
THROTTLE MAPPING
IE engineers have mathematically rescaled the entire mass flow model over 30 maps which corrects the entire throttle input range. This extensive remapping work delivers a linear and predictable throttle pedal with clean and linear boost delivery, which improves drivability in any scenario.
EGT OPTIMIZATION
ECU programming uses exhaust gas temp (EGT) readings to make air/fuel corrections and determine the health of the combustion cycle. Countless development hours were spent adjusting boost, air/fuel ratio, ignition timing angle, camshaft phasing, intake air temps, and much more to develop the proper EGT adjustments for every octane file.
Enjoy power gains from different fuel options knowing each was individually optimized to provide reliable engine operation without sacrificing power.
VE MODELING
The factory 2.9T engine's MG1 ECU relies on a complicated volumetric efficiency (VE) model to convert boost to engine load and accurately deliver fuel for various conditions. Instead of depending on fuel correction tables to compensate, our calibrators have remodeled the VE mapping for the new boost/load relationship. This extensive work delivers reliable and proper fueling and smooth power delivery you can feel.
