PORSCHE 4.0T ENGINE TUNE

IE's premium performance engine calibrations reprogram your Cayenne's Engine Control Unit (ECU) to instantly release hidden power from your twin-turbo V8 with 692-857HP and 795-893ft-lbs of torque! Enjoy a transformed SUV that feels like a proper Porsche with maximized power, a snappy throttle feel, improved boost delivery, reliable engine response, and a larger powerband. Engineered to operate on entirely stock hardware or with an upgraded intake and intercoolers for the most performance.


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.


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.

Doesn't really slip on too well.
Size: 11, Color: White, Size: 11, Color: White
Doesn't really slip on too well. Also, since the heel is ridged it unintentionally allows my heel to slip out while walking.

Really like these for casual summer outfits
Size: 10.5, Color: White
These are really nice kicks. Stylish, comfortable, and eye catchy for sure. Not too heavy, good price, and fit well. These are great, casual white shoes for a summer outfit. I gave it 4 out of 5 stars as these do pick up and hold onto dirt and smudges more than I’d like to see. Yes, I know, white shoes are magnets for this stuff, but these tend to scuff and discolor more than I would have assumed. I live in an area with lots of bad weather most of the year so I only get a chance to wear them for a few months of the year unless I want to brave the wet and muddy weather. If you live in an area that has lots of sun and are willing to put these to the test and clean them often, I would say go for it.

Poor quality

Bottom of shoes after three weeks worn already have a hole in it! Didn’t expect to have to toss them away so soon.
