I drove in normal mode for the first month or two after I bought mine just to let it get a good break in before I started driving how I like. Now I drive exclusively in Sport mode and I’ve noticed zero loss of MPGs. I honestly feel like Sport mode is actually “true normal” and all the other modes are modified. In normal and eco, throttle is slow to respond and the transmission is always early downshifting. Tow mode is, well, for towing. But Sport mode is untainted by electronic interference. Throttle response is better. The transmission shifts better and doesn’t skip shift near as much. Fuel efficiency is unchanged and I have better control of my truck without the cylinder deactivation or auto start/stop annoyances. Win win
