No idea maybe my gearing? It’s set up for highway driving, I think it’s 3.23’s in it, I gotta check the window sticker. But also I’m at relatively low elevation less than 1,000’ so I’ll see better MPG than say someone in Colorado.
this was also when the truck had less than 2,000 miles on it. Now I have about 7k. Those 20mpgs are gone with the lift and tires.
