Well I've been lurking the past few weeks as I've adjusted to the new car, and as a daily I find almost no fault (other than it gets the same mileage as my GT before it was modded), however it is rather boring, especially in the low end. After having a talk with a local custom shop I've decided to go all out with my edge. My overall goal of this build is to be a competitor to the Cayenne Turbos, both inside and out. Before the inevitable questions of "why" and "are you insane", yes I have the means for this build, and it'll be staged over the course of probably a couple years due yo custom work and waitlists alone. So my initial questions are for mild mods to tide me over until she goes under the knife. Topping the list is low end power. It is atrocious in these cars, what have people done to remedy that? I've seen the livernois tune that supposedly picks up a ton in the low end, does anyone have first hangs experience with it? I also saw HR lowering springs and have found plenty of excellent reviews on for a temp setup before air suspension, anyone out there have any negative experience or any reason to not go with them? Does anyone make a big brake system, I've seen these cars lowered on larger wheels, and the stock brakes look a little ridiculous with anything larger than stock. Last but arguably the most important, does anyone know the exact mechanical differences between our NA engines and the ecoboost setup? (Secondary to that, does that awd system get any improvements between the two?) Thank you all in advance, post up pics of your modded setup too!
