Default speedo is fast
so my speedometer reads 4 to 5 mph to fast based on using a GPS unit. Do I need to increase my driven gear 1 tooth? Or decrease my driven gear by 1 tooth? I'm thinking, go from a 22 tooth driven gear to a 23 tooth driven gear coming out of the T5 tailshaft. Anyone have the facts? Thanks
