Please Note: IE PowerLINK V4 Flash Cable must be purchased separately. The cable can be purchased here

IE's 4.0TT ECU tune for the Porsche Cayenne Turbo and GTS V8 is a total transformation delivering supercar performance with 692-857HP and 795-893ft-lbs of torque depending on octane. With our cutting-edge modern motorsport tuning approach, your twin-turbocharged engine's potential is fully realized while maintaining total comfort and reliability. Release the hidden power and heighten your driving experience with a simple install that takes only minutes from your phone.

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.

An ethanol content sensor kit is highly recommended when running E40 ethanol blends. 

MAXIMIZED OUTPUT
This is not a simple dyno tune. IE's in-house calibration systems were used to reverse-engineer the factory ECU mapping on a professional OEM motorsport level. This grants our calibrators access to every ECU mapping parameter and the ability to add custom programming as necessary. Additional sensors and data collection systems are added as required to completely realign all safety protocols and sensors for the new max-performance ECU tune. 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!
