Ok, I know that Elite and DJ have some kickin race tunes, but I have a buddy that wants to get a tow setup. He has a 2004 f350 with a 6.0 and a manual trans. He has a dead spot in the rpm band that he wants to eliminate. He just wants to do a good tow tune to liven it up when pulling his horse and hay trailers. It is pretty much stock, but we will be putting an exhaust and intake on it in short order.
