I got my car back today from the installer.He installed the ford 4:10 gears.I asked him about the odomiter and speedodomiter be redone and he told me i needed a chip.....i couldn't use a speed cal on my car.I have a 2002 Gt 5 Speed.Is this true?From all the posts i was reading on here i was under the impression that i could have used the speedcal to reset my speedo and odomiter.Can i use the speed cal on my car?Will it reset both my speedo and the odomiter?Or do i need a chip?Thanks Shane
