Everything I've read here is that people pick up 1-2 mpgs MAYBE. It does not make sense to pay 50-80 cents more a gallon to get 1-2mpg more.Those who say i dont need that much performance are probably looking at it like a number. Instead of doing that look at it as the amount of efficiency that the truck has. Even without a tune the overall efficiency will go up with premium fuel.
