i have almost 6k miles on mine and i have never gotten above 13.3 mpg and i drive between vegas and cali on open freeway for 600 mile stretches i dont see how this 7mpg diffrence is possible? even if i drive more aggressivly and have a tune? are u never driving ur truck in "m" more or moving ur shifter to the left and engaging "sport" mode? even if not it still seems like an impossible discrepancy imo. i just cant stand driving my truck in non sport mode, it has such a terrible throttle lag and by 40mph its already in 5th gear.
