The guy I bought my 2002 F350 4x4 LB diesel from called me and said his wife found a programmer for my truck in some boxes. He said he forgot all about it and it was in the glovebox when he bought the truck. He didn't know what to do with it and put it in a box. I'd say I would believe him because I bought the truck back in March, so he didn't have to call me. I knew it had to have something because my other 2002 that I had didn't run like this one. Who has used the Superchips Prgrammer 1705 for the Ford 97-2002 diesel. Is it a good one and if not what one would be reccommended?
