Default speedo too slow?

Took the my 93 auto to the track yesterday(first time since H/C install) Ran a 12.45@115.8(2.02 60 ) When I crossed the finish, my speedometer read 106mph Under further investigation, Playing with the throttle, The speedo will only go up in increments of 6mph under full throttle. And from a dig it wont register at all. It will sit at zero for 3 seconds as im blasting off the line and then start at 25mph and go in 6mph sections. Is there a cable or a trans gear that will fix that?
