NO LIMITS – NO COMPROMISES
Audi leaves a portion of its performance untapped by default. iE tuning software unlocks this potential by safely reflashing the engine control unit. The result is stronger acceleration, more precise throttle response, and a completely new driving experience – all backed by AutoProtect protection.
739 hp – DONE RIGHT
iE B9 3.0T programming offers up to 505 hp power increase with the stock turbo, and up to 739 hp with a Stage 3 turbocharger. Unlike low-quality tuning, power increases smoothly and controllably without sudden power spikes, hesitation, or jerky operation.
Acceleration is powerful, throttle response is precise, and drivability is refined for everyday use. Smooth and sophisticated at cruising speeds – relentless when the throttle is floored.
FAST, NOT RECKLESS
This is not a single dyno file rushed together or a cautious, one-size-fits-all generic program for every car. iE software is developed over months of work and tested in real vehicles, in different climates and varying driving conditions around the world.
AutoProtect continuously monitors critical engine operating parameters and immediately reduces power if necessary. This gives you access to significant performance while operating with built-in protection.
CUSTOMIZE THE SOUNDSCAPE
Enable the Exhaust Crackles function and give the Audi 3.0T engine more character. The function produces impressive pops and crackles during engine braking and gear changes.
Change the settings instantly via the app or CarPlay: add more crackles, tone down the sound, or turn the function off completely in real time. With exhaust valve control, you can reduce annoying drone or open up the full sound of the exhaust system at any time.
Exactly the sound you want, exactly when you want it.
MORE THAN JUST AN APP
Take LIVE tuning further with the POWERlink app, using CarPlay, widgets, and Siri. Use supported adjustable functions quickly and conveniently with controls suited to your driving style.
NO MORE TURBO LAG
iE Anti-Lag increases boost pressure before the car even moves, enabling powerful, sustained all-wheel-drive launches. Rolling Anti-Lag (RAL) offers the same benefit while driving, making power immediately available from a rolling start.
You can adjust the idle RPM directly from the app, the cruise control stalk, or via CarPlay, and customize the settings for different driving environments.
ADJUSTABLE THROTTLE RESPONSE
The default setting for iE software is predictable and balanced throttle response. If you want more control, you have 15 customizable settings, allowing you to choose between smooth, linear or sharp, immediate throttle response.
Changes take effect immediately, so you can switch from economical to aggressive driving at any time.
One tune, multiple driving styles. No extra standalone control devices.
TRUEFLEX: E85 ETHANOL MADE EASY
Ethanol offers significant performance potential for S4, S5, and SQ5 models, but using it should not require complex calculations or constant adjustments.
iE TrueFlex™ brings genuine flex-fuel functionality, which detects the ethanol content of the fuel and instantly optimizes boost pressure, ignition timing, and fuel delivery. This allows the engine to safely deliver the best possible performance based on the fuel in the tank.
No measuring. No calculating. No reflashing.
Fill up with 91/93 octane gasoline, pure E85 ethanol fuel, or any blend of the two. Fill up and drive.
BUILDING THE PERFORMANCE
The path from a stock car to a true performance machine
1. STAGE 1
Achieve up to 446 hp with Stage 1 ECU programming alone using 91 or 93 octane fuel. Power can be increased even further with optional TrueFlex ethanol updates.
Combine the programming with an intake system to improve airflow and give the turbocharger a pronounced sporty sound.
*Included in Core, Pro, and Apex packages
2. STAGE 2
To safely maximize stock turbo performance, a downpipe, intake, and intercooler are required.
Improved airflow and more efficient cooling help keep power consistent, while acceleration improves across the entire rev range. Add a catback exhaust system to the setup to make full use of the adjustable exhaust crackles.
*Included in Pro and Apex packages
3. STAGE 3
Build performance without compromise. Moving to larger TTE810 or Pure750 turbos, which replace the originals directly, requires an intake system, intercooler, downpipe, and turbo inlet pipe update, as well as the iE Stage 3 Map Pack software package.
The complete setup delivers an incredible 613 hp!
*Requires the Apex package
4. STAGE 3 PLUS
When performance is paramount, the Stage 3 setup can be taken even further with 4 bar MAP sensors, a high-pressure fuel pump (HPFP) update, and larger 4.0TT RS injectors (Audi part number: 06M906036AD).
To achieve maximum power, E70 ethanol fuel and the iE TrueFlex Kit are required.
The result is 739 hp, exceptional high-RPM performance, and relentless all-wheel-drive acceleration. This elevates the 3.0T engine into the supercar performance class.
