My two cents. I leave mine in Smart Mode all the time, and it's just dandy. The fly-by-wire has a bit of lag, but not problematic. If I ever feel like spending a few bucks I may add a Pedal Commander. I have noticed, when playing with Sport mode, that the engine stays reved significantly higher than in Smart mode (like 1K more). So that alone tells me the gas mileage will be less. But it is definitely more responsive in Sport mode.
That pedal commander is legit, I have one in my Wrangler. I need all the help I can get with that lumbering beast.
