LOL! What I've heard (I have no first-hand experience to back this up) is that the "ghost cam" tune only affects parameters at idle. The mapping for any throttle position above idle is the same as it otherwise would be without the ghost cam, i.e., it just turns into a "regular" coyote as soon as you step on the gas. So, the question of how much the ghost cam affects fuel economy comes down to how much of your driving is stop and go where you're sitting at idle. FWIW - I've also read that the ghost cam tune is really rich at idle - so much so that it'll kill catalytic converters (if that's a concern).
