IE Stage 3 ECU Performance Engine Tune For C7/7.5 Audi S6/S7 4.0T EA824

Take control of your Audi S6 or S7 by unlocking thrilling power and acceleration from your phone! Our cutting-edge engine and transmission tunes transform your car through the innovative POWERlink Bluetooth dongle that plugs into your vehicle's OBD II port. Our responsive mobile app links the dongle to your Apple or Android phone, giving you the power to tune your car, change octanes, upgrade stages, perform diagnostics, monitor live gauge data, and more —all from the palm of your hand!

Designed for the dedicated horsepower enthusiast, our Stage 3 tune utilizes larger factory RS7 turbos to deliver an extended powerband that sustains power to redline with incredibly fast torque onset. Despite peak power numbers remaining similar to our Stage 2 91/93 pump gas tunes, the broader powerband pulls hard to redline, far surpassing stock turbos. For the serious horsepower junky, Stage 3 truly shines on E85 and 104 race fuel, reaching an impressive 719HP and 768ft-lbs of torque! Enjoy a new addicting powerband with minimal lag and remarkable acceleration that will keep you glued to your seat, all while retaining comfortable daily manners on your everyday commute.

Let Your V8 Roar!

Your Audi S6 or S7 has a powerful twin-turbo V8, it's time to sounds like one too! To help accomplish this, your iE Tune includes two optional features on all stages that will make your eight cylinder turbo sound like the king of the streets. Add the motorsport-inspired Exhaust Crackle to your exhaust note or the iconic lopey idle with Ghost Cam. These addicting features exist purely to add more fun and excitement to your drive and can be turned on or off at will through your POWERlink.

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. Although full E85 is recommended for the highest power output, safeguards are included within the E85 ECU calibrations to adjust for ethanol as low as E60.

E60-E85 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.

Cylinder Deactivation

The factory ECU calibration includes many compromises removed by your IE Tune. One of the most problematic is the stock cylinder deactivation which attempts to increase fuel economy by only running 4 cylinders when cruising. This causes rough shift, loss of power, and is believed to cause early failures of motor mounts. Cylinder deactivation is completely turned off by default.

Cylinder deactivation can be reactivated on request.
