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.Â

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.
EGT OPTIMIZATION
Exhaust Gas Temperature (EGT) is the measurement of fuel mixtures exiting the exhaust and is used to determine the health of the fuel/air mixture entering the engine. IE engineers have spent countless hours adjusting boost air/fuel ratio, ignition timing angle, camshaft phasing, intake air temps, and much more to develop the proper EGT adjustments for ultimate engine safety without sacrificing power.
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!

IMPORTANT INFORMATION
TUNE UPDATES
Your tune purchase entitles you to free updates to any tune revisions, new octanes, standard features, or software updates. In the event the original vehicle manufacturer issues an ECU update, this will also be included to you through IE at no additional charge.
POWERLINK VINS
Have multiple cars in the family or friends that are also ready for an IE Tune? Your POWERlink Flash Tool can be used on up to 5 different vehicle VINs. Tunes sold separately.
TUNE REGISTRATION
Once a tune purchase is applied to your vehicle’s ECU, the tune is permanently registered to the vehicle and non-transferable to other vehicles. Tunes can be transferred to a second party in the event of vehicle transfer of ownership only.
REQUIRES V4 IE POWERLINK
The Porsche ECU uses new and updated flashing protocols to read and write the engine calibraitons. Older V3 IE POWERlinks do not include the required internal hardware need to flash the 4.0T engine calibrations. If you are purchasing credits with an existing IE POWERLINK, please be sure your serial number on the back begins with V4.

Important Note: Porsche is implementing new security patches in the EA825 ECUs. Only some security patches have been fully cracked by the aftermarket, and some vehicles may require additional work for IE’s calibrators to flash. If your car is equipped with a rare ECU, you may experience a brief wait period while our calibrators bypass the security patch.
