I bought this programmer about a year and a half ago for my 2002 F-250 w/ the 7.3 Powerstroke. I'm moving on to a newer model and I don't need this programmer any longer. The programmer is like new and I still have the orig. box and owners manuel. This programmer is very simple to install. You just plug it into the trucks ECM and follow the directions on the backlit screen. This programmer will give any 7.3 Powerstroke Diesel a 60-100HP gain depending on the setting you desire. I have noticed that my mpg icreased from 15.4 to 17.8 mpg while programmed in tow mode. I'm asking $300.00 (obo) for the programmer or may consider trades for VTX accesories. I have a 2004 1300C. I will also ship free anywhere in TX.
