Well my mph seems to be off around 10 mph around 40, as in , Ill be driving about 40-45 and my speedo says 50-55, Now I did the 5 spd swap and read that you keep your speed sensor gear to your rear end gears. So I took my auto speed sensor and put it in the 5spd, as i kept my auto 3.27 rearend gears which is an upgrade to the 5spd, stock factory 5spd had 2.73? correct? anyways my speedo is off and dont know why? any help is appreciated. also I dont really care but i need to smog the car also, when they do the test do they go off the the car speedo? Or there computer? when they do the 15 and 25 mph test??thanx
