I changed the final drive ratio to 3.73(new ratio) under the speedo category...Is that all you do to make the speedo work correctly after new gear install...It still seems a little off....people are flyin past me and it says Im doin 60..maybe they are just goin way faster lol...

Di you have mile markers and a stop watch? You can also check your RPMs with a gear calculator gears

do you have to change the tire size or something? I noticed that its different between the stock file and the file that I changed to 3.73...it recalibrated the tire size itself...does it need to be stock value?????? still seems Im doin way slower than what speedo says...
