I have a 2006 F-350 Super Duty flat bed. I am looking to put a tuner on it to help out. I am not looking for a speed racer but this is truck I drive on a daily bases back and forth to work and so on. I use this truck as well for pulling my horses from arena to arena for team roping events. Most of all I am looking for something to help on the gas millage. By me telling you all of this can you give me an idea of what tuner you would recomend. All by the way I do have a cold air kit on this truck everything else is factory.
