IE Stage 3 ECU Performance Engine Tune For B9 Audi RS5

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.

The iE Stage 3 engine and transmission tune for PURE800 turbochargers completely redefines your RS5’s performance. Every element of the calibration is engineered to extract maximum power and torque while maintaining the smooth drivability Audi is known for. Our advanced tuning strategy optimizes boost control, ignition, fueling, and torque management to deliver an exceptionally broad, flat powerband with near-instant response and negligible lag. Paired with our matching TCU tune, shifts are faster, smarter, and perfectly balanced to harness every bit of performance. The result is an RS5 that feels factory-refined at cruise—and brutally fast when you demand it.

EFFORTLESS E85
Ethanol is rocket fuel for your daily driver. Our TrueFlex flex fuel conversion kit upgrades the factory engine computer to read and instantly adapt to any ethanol blend, unleashing huge power.

ANTI-LAG LAUNCH
Gain the boosted advantage with iE’s advanced anti-lag launch and rolling launch control standard on all stages. This custom-coded strategy build boost before takeoff, delivering an aggressive launch that shaves down acceleration times. Fine-tune your launch with instant launch-RPM switching and adjust your launch point in real time to match tires, surface, and conditions without reflashing. For roll racing, rolling anti-lag holds a set RPM and speed while building boost to unleash instant power and gain the upper hand when it counts.

ADDITIONAL TUNE FEATURES

ETHANOL FUEL
Ethanol fuels are included and unlock the most performance potential from our ECU tunes. Ethanol contains tons of oxygen, burns cooler, and has a high resistance to knock. This provides more horsepower and torque than running conventional gasoline and is much less expensive than race gas.

Ethanol options available on all stages

BRAKE BOOST
Commonly used in roll racing, Brake Boosting allows you to build extra boost by applying brake pressure while accelerating. Release the brake pressure for a "rolling launch" or extra surge of power.

Brake Boost is included on all tune stages.

AUTOPROTECT
Even with the best tuning, unreliable fuel and mechanical failures still pose a risk to any engine. iE AutoProtect is your last line of defense against engine damage. If trouble pops up, AutoProtect lowers boost and power to keep your engine safe against damage. When conditions return to normal, power automatically restores. Our unique error code is triggered so we can help pinpoint the problem. LEARN MORE
