iE Stage 1 ECU calibration is a straightforward flash-only enhancement that instantly adds excitement to your S6 or S7. Stage 1 raises the rev limit, increases boost pressures, and more, leading to dramatically quicker 0-60 times and enhanced acceleration in any scenario. This sophisticated engine calibration seamlessly integrates into a completely stock car or will automatically adjust to maximize the benefits of optional intake, heat exchanger, and intercooler upgrades.

The C7 4.0T engine is outfitted with sizable and effective factory downpipes that are already capable of maximizing power and exhaust flow capability from the stock turbos. Although Stage 2 tunes don't yield extra power gains on this platform, Stage 2 offers vital ECU calibrations to accommodate aftermarket downpipes. This is perfect for users desiring a more aggressive exhaust note and incorporates an improved exhaust overrun/crackle feature in dynamic drive mode.

• Louder V8 exhaust noise with downpipe upgrades
• More aggressive overrun/crackles with downpipes

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.

• Stage 3 designed for factory RS7 turbochargers
• Minimal boost lag increase
• Larger powerband all the way to red line on pump 91/93
• Massive power gains on ethanol and race fuel
• Well beyond stock RS7 power for your S6/S7

All iE ECU Tunes for C7 S6 & S7 require our matching iE DL501 DSG Tune. When tuned, the large 4.0T V8 delivers substantial low-mid range torque gains, exceeding factory DSG limits, leading to clutch slip and power loss. The iE DSG tune increases line pressure and torque limits well beyond stock to handle the power increase safely. This comprehensive transmission tune also ensures lightning-fast shifts, optimized points, multiple launch-control modes, and enthusiast drive mapping. The engine and transmission tunes fully transform your Audi for faster launches, higher Gs, and improved acceleration.  

iE DSG tune is required for Stage 1 & 2 ECU tunes.

• Increases torque limits and clutch pressure for tune gains
• Optimized shift points for fastest acceleration in drive & sport
• Lightening-fast shift times
• Removes first gear lockout when downshifting
• Faster paddle response times in manual shifting mode
• Optimized launch control RPM to control tire spinning
• Gear hunting is greatly reduced
• Temperature protection optimized for safety
