I just bought a 96 mustang gt and it has different gears so I bought a superchips micromax programmer to adjust the speedometer. I had one that I sold with my other mustang worked great. I was starting to tune and after asking if I had fuel pump fuse removed answered yes it said error code 6 contact superchips I have done this no reply I was wondering if anyone can tell me what error code 6 means on the programmer. Don't want to install a tune just adjust my speedometer for the new gears. Hope someone can help. thanks
