There you go. Your information agrees with the previous owner of my truck. It could be that the truck Kevin speaks of just wasn't a good one to start with, especially one to try to beat a fuel economy record? Every truck is different..one of the reasons Tony Wildman is reluctant to advertise HP increases with his chip. I get such poor fuel economy, I am always asking others what they get. Stock 7.3s can get 21 MPG all day long. Add a few mods to improve this and keep your foot out of it and 24 MPG is certainly a reasonable possibility.
