Default Increase In Fuel Mileage

Since I moved to Indiana I'm up to 20mpg from 15ish in Alabama. I figured this by checking the fuel volume at fill-ups versus the odometer mileage. I've checked the odo, its consistent with how it measured before I moved. Nothing else has changed and the truck behaves the same. What could give this gain? I'm not complaining, but still, I'm very curious.

Have you put injectors in the truck in the last couple thousand miles?? My fuel economy bumped up a little after a 1000 miles or so since they were new and not remans, remans use used springs and are already "broke" in but brand new ones will break in at different times and sometimes the pop off pressures will vary until they are all broke in
