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 builds turbo 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

EXHAUST OVERRUN
The stock calibration features a very mild overrun/crackle when you decelerate from higher RPM, but is very hard to hear with factory downpipe/exhaust. Stage 2 & 3 files turn up the aggressiveness of this overrun and enable crackles on free-revving in neutral or park. Not only will your car drive faster, it will sound faster too! Guaranteed to put a smile on your face.
Exhaust Overrun is included on stage 2/3 tunes.

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.

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.

STAGE 3 TUNE OPTIONS
iE offers two levels of hybrid turbo upgrades. Stage 3 is designed for pump gas fuels on all stock fueling hardware, essentially this is a Stage 2 hardware plus hybrid turbo setup. Stage 3 Plus goes all out with fueling upgrades to maximize power on ethanol and TrueFlex. Each level delivers more fuel and offers increasingly higher power output. Use the slider below to explore Stage 3 options and the additional hardware required for each.

STAGE 3
iE Stage 3 offers an easy upgrade into hybrid turbo power levels on pump fuel (91 & 93 octanes) with only the turbocharger upgrade and stage 2 hardware (intake, turbo inlet, intercooler, & downpipe). This setup delivers deceivingly fast performance without additional fueling upgrades. TrueFlex requires Stage 3 Plus.

Hardware Guide:

Required:

• UPGRADED INTAKE (IEINCK3)
• INLET W/ HYBRID ADPATER (IEINCK4)
• UPGRADED INTERCOOLER (IETPCK1)

Optional:

• UPGRADED DOWNPIPE (IEEXCK3)

SUPPORTED HYBRID TURBOS
iE engineers and calibrators valued fast boost response, top-end power, and a robust build when selecting a supported turbocharger as the base for our Stage 3 tuning. After extensive research and testing, we found the best hybrid turbo options that offer a unique combination of big top-end power and responsive boost with very minimal lag, all wrapped up in an easy direct bolt-in install. Combined with iE's calibration strategies, the result is a perfect marriage of modern vehicle tech and raw chest-pounding performance. Turbo sold separately

STOCK DOWNPIPE FILES
Looking for serious performance gains while keeping factory emissions in check? iE Stage 3 ECU tunes include optional files specifically for use with a stock downpipe. Both Stage 3 and Stage 3 Plus tunes deliver the same impressive power on pump gas (91 and 93 octane) as they do with an aftermarket downpipe. Running E70 ethanol? You’ll see up to 79 HP and 53 ft-lbs less than with an aftermarket downpipe, making it a great balance between power and emissions compliance.

INCLUDES TRUEFLEX
Ethanol-blended fuel provides the maximimum power for iE Stage 3 Plus Hybrid Turbo Tuning Suite. TrueFlex adds our advanced flex-fuel programming to your engine control computer, automatically adjusting engine mapping in real-time to match the exact ethanol blend, eliminating guesswork, and ensuring maximum safe power at all times.

• REQUIRES TRUEFLEX SENSOR KIT
• REQUIRES STAGE 3 PLUS HARDWARE

STAGE 3 TRANSMISSION TUNE
iE Stage 3 and Stage 3 Plus far exceed the factory set transmission torque limit and requires a complete matching transmission control unit (TCU) calibration. IE's matching Stage 3 TCU tune fully harmonizes the complete drivetrain for the hybrid turbo characteristics with optimized shift points, further increased RPM limits, faster shift speed, user-selectable launch control, new drive-mapping, and more.
Stage 3 TCU Tune is a free upgrade from Stage 2 TCU

Important Notice: 2021-2024 (B9.5) model years have limited TCU tune support. Some transmissions are equipped with advanced security locks and cannot be unlocked for tuning. Before purchasing a Stage 2 or 3 TCU tune for these model years, please follow our easy step-by-step Audi B9.5 TCU Unlock Guide using your iE POWERlink Suite App.
