Yeah i know for a fact i was 5mph off cause after i went from 31 to 33.5 i was beside a buddy and his cruise was set and mine was reading 5 mph off.

I got it fixedthis weekend. For 39 bucks and some elbow grease. I took off the speed sensor and switched out my stock speedo pinion gear for one with more teeth. I used a calculator and found out i needed a 36 so i switchedit and its right on the money! I used my dads gps today and it was right on with it!!! Not even 1 mph off! here are some pics.
