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         HARDWARE GUIDE Unlock the full potential of your ECU tune with our comprehensive range of iE hardware upgrades. Each tune stage is designed to work seamlessly with optional or required hardware, maximizing the enjoyment of your Audi 2.9TT engine. While Stage 1 doesn't require any hardware upgrades, adding our intake, turbo inlet, and air to air intercooler will result in increased airflow, lower intake air temperatures, and quicker heatsoak recovery, leading to a more efficient and faster vehicle overall.
