    speedo all over the place

    i have the teleflex guages. just bought them from somebody on here because my others were messed up. they are that newer and improved version apparently.

    i put them in this weekend and all the numbers, letters, etc are fine...no missing or impartial. however, the speedo is registering like 68 mph! thats pretty dang good for sitting on the trailer. it bounces around a couple miles an hour just sitting there. ie 66-69. has anybody had this problem, know what it could be. i read something on here about a control module/box that the pitot tubes come into, maybe that is bad???

    i generally just use rpms but i figured id try to figure it out since the guages are 'new'

    any help or ideas are appreciated.

    2001 super sport if that makes a difference.

    Look at your ground wires That may be the cause. Make sure the plug is plugged in all the way.
