What is the best tuner for fuel mileage for a 2008 F450? I am getting 11 miles to the gallon and she is a everyday driver. Need help and dont want to break the bank. I had an edge in my lifted F150 and it produced for me. The problem is i have ready on this forum that they are no good for diesels. Like I said I am new to the Diesel Game and truly dont know much, just enough to get me into trouble. All help is appreciated.
