Default speedo gear

Speedo reads about 12mph higher then GPS so my question is simply would I change speedo gear to more teeth or less teeth

How is the odometer-- if that reads correctly the problem is in the speedometer, not the gearing la

If you let us know your wheel size and rear-end ratio we can tell you what your speedometer gear "should be". Then if it doesn't read correctly the problem would be in the speedo not the gearing.
For example, a 30-31 with 19" wheels and 3.78 Rear (Standard) would use an 18 tooth driven gear in the speedo turtle
