If it was fine before and is just off now, sometimes that just means you need a new speedometer cable, or even just to re-position or re-lube the existing one.

yeah i have that one, i think the overlay gauges might have been off by a tad on the rpms, so cant line everything up. i have one in now that compensated the tires but im going to new axles this summer as well.

Unfortunately it's not electronic so no way to "program" it. There was 1 old time member here that converted his 1st gen to OBD2. I can't remember who it was & a search didn't turn it up, but he replaced the engine trans & ECU with a 2nd gen & swapped over the OBD2 system. A lot of work but he had a few donor trucks. 410fortune comes to mind....not sure if it was him.
