I changed the oil about 1000 miles ago,fuel filter 900 miles ago, I keep the tire tire pressure at 50psi, I just cleaned the air filter and I have the programmer set on the highest setting right now, I have tryed all the other setting and the mileage doesn't change. I never have got go mileage with the truck except when I went through the rocky mountains in Colorado and then I was getting 17.6 mpg,and that was before all the mods. I never got good mileage when It was bone stock. The only thing I can think of is that the motor is not broke in yet.
