Hello, new to the forum. Long time reader. I’ve been reading up on everyone’s mileage per gallon and I’m embarrassed. I can pull 12-14mpg empty. Mostly highway miles, running in my level 1 fuel economy tune. Granted my truck having wide wheels and being leveled doesn’t help. But 14mpg just isn’t right. I was wondering if anyone had tips or tricks for me? I drive pretty nice to get these numbers and I want to do something about it. I know there isn’t a 100% way to get 20+ mpg but I should be getting better than this don’t you think? All my mods are in my sig.
