Default Speedo gear.

I did the spin the wheel watch the driveshaft trick to make sure and I know that I have 3.73 gears. I ordered a 3.73 correction gear and my speedo is still over by about 10mph. any ideas? I have larger wheels than stock so i assume that the problem, so how do I get it right?

Larger wheels and tires should slow the speedometer down. Are you sure you got the right one.
