Message: [QUOTE="Powerstroker6.4, post: 1214704, member: 18389"] I was doing fine on the 250 Spartan tune, but decided I wanted to see if better mileage was possible. After switching to the 300 tune, the gauge actually was showing that for every 1/3 of a mile I traveled, I was really losing a mile on the guage. Thinking that was horrible, I switched back to the 250. Even then the mileage sucked!! Is that really that normal, or is the gauge off?? It depressing to watch the gauge! LOL [/QUOTE]
