Like I said, I didn't change anything. I'm aware of all the variables that can change gas mileage, including driving habits and style, speed, road conditions, weather included to what you've mentioned. Even with some changes to those variables, going from 22 MPG to 27 makes me think that there's more to it, and mostlikely perhaps a change in tune to maximum fuel efficiency.
