Wondering if anyone can help. I just ordered my new 2013 F250 Platinum 6.7L and although the gas milage is pretty good on it (I drove my friends home from the dealer for him the other night), I heard that some performance chips can jump 5-6MPG. The chip Im looking for is simply for MPG, I dont need to mess with HP "YET". I was also told to look with one with a ghost mode that I can use for to save my warranty...
OK...GO! What are your suggestions?
