INCLUDED OCTANES

Effortlessly switch between octanes at your convenience with IE POWERlink Mobile. IE Cayenne 4.0T tune offers optimized files for 91, 93, 104, E85, and E40 fuels, ensuring maximum power and torque from your fuel choice in just minutes.

E85 &104 RACE GAS

The E85 fuel map allows easy ethanol fill-ups without mixing ethanol/gas blends. Just fill up your tank with E85, flash the E85 tune option, and experience the massive increase in power over regular 91 or 93 pump gas. Our 104-octane race gas file has been developed with Sunoco GT260 Plus 104 for areas without or with limited ethanol availability to offer considerable power gains without using E85.

E40 ETHANOL BLEND

Release an absolute torque monster by combining 91/93 pump gas with E85 to 40% ethanol (E40). This blend creates a safe fuel mix that stays within the limit of fuel delivery for the factory injectors. This E40 calibration produces the total torque output from the twin-turbo V8, producing an exhilarating 893ft-lbs of torque with seat-slamming acceleration.

ADVANCED TUNING

The factory ECU calibration is full of regulations and compromises that limit horsepower/torque and dull the power delivery and throttle feedback. IE calibrators re-tuned the complicated boost map programming with advanced strategies, resulting in unmatched power delivery. The throttle mapping also receives a significant rewrite to deliver a linear and predictable throttle feel. These refinements result from months and months of fine details that dramatically improve your control over the car with a much more connected and precise feel.
