    Had my conversion done for several years now, standard 3 on the tree. Is there away to adjust/correct the speedometer?

    Thanks Steve

    The easy way is a speedometer ratio adapter. Just type "speedometer ratio adapter" into your favorite search engine.

    Go to TCI "speedometer gear calculator" to get the correct speedo drive/driven gear formula and eliminate any ratio corrector. Your speedo is reading too slow now so what we do now is to use a gps to find the PERCENT difference between indicated speed and actual speed and then use a set of gears that will read that percent faster.
