- Doesn't take a GM pro. Go to any speedo shop (look in yellow pages) and
- they will put your car on a roller and calibrate your speed. Then, for
- a small additional fee, they will pop in the correct speedo gear. Worked
- for me, I went to a little taller tire, speedo read about 5-6 mph slow,
- switched the gear, works fine.
-
- At a 60 mph correct, 82 mph indicated, you're going to have to go to a speedo
- gear with a *lot* more teeth. They may not be able to put in a gear that will
- adjust ~35% by itself, but I'm not sure how much range there is to work with.
