Stage 1 is designed for vehicles with stock hardware and will fully release all performance potential available from the stock turbochargers and engine. While no hardware upgrades are required, upgrading to a performance air intake system will net additional power gains of up to 40HP over stock!  

See the performance tab for power results and dyno charts.

Stage 2 is a full performance calibration to account for aftermarket downpipes looking for increased exhaust sound for track use. Due to the efficient 4.0L engine and stock turbo sizing, factory downpipes are not a restriction and upgrades do not increase power over Stage 1 with upgraded intake numbers. See below for a complete list of Stage 2 requirements.

E85 fuel unlocks the most performance potential from our ECU tunes for your Audi S6 or S7. 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 more readily available (in most states) and less expensive than race gas. E85 is an optional fuel map included with all tune purchases. 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. This flexibility gives you the confidence to safely fill up at the pump which can commonly test lower than advertised.

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. If you want to keep cylinder deactivation, we will reactivate on request.

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 with your IE POWERlink.

IE's fully proven software brings track-ready ECU programming to your turbocharged V8 engine while retaining factory comfort and reliability. IE's own tuning technology suite is used to completely reverse-engineer the factory ECU mapping, allowing our software engineers access to realign all safety protocols and sensors for the new performance calibration. Every tune parameter undergoes months of testing on our in-house dyno systems that utilize the world's only Sea Level Generator developed specifically to verify tune operations in any condition. Confidently drive from LA to Pikes Peak with power that will keep you smiling every mile!
