I am interested in the Ford Racing tune that supposedly does not affect your warranty if you have your dealer do it. I understand this is a milder tune than some of the others available, but that's more or less what I'm after, since my car is a DD.
One subject I've not seen addressed is the effect on fuel mileage of these tunes. I suspect mileage is reduced but not sure.
