Hey all, just got my tunes for my Autocal and tried loading them in last night with no luck. I've emailed my tuner but thought I'd get some insight here as well, maybe its a common problem and I'm doin somthing wrong.
I tried with all fuses in, i tried with radio fuse out, i tried with radio, info and two others my old bully dog programmer had me pull. Fails every time, i'm getting codes $0281, $0322 and $0533. Anyone have any input on this? 03 LB7 Duramax
