road speed constant/tunerpro rt
Correct me if im wrong, but on my 93 if i was to go to say a 3.73, and changed the road speed constant in tunerpro, all that would do is change the speed the ecm is seeing and not actually change the speedo? would i need to change a speedo gear in the trans? thanks in advance.

if I remember right, the speedo/tach sensors are all electronic on the cars now. No speedo gear. So yeah, change what the computer reads and you will be fine.
