I had 4.30s installed last week and am trying to correct the speedometer and odometer...so i bought the following speedcal:

The mechanic installed it and put the 3 dials inside the box to 760 (based on this installation sheet - we used method 1 on page 8, which says to take the 3.27 divided by 4.30 which equals .760): http://latemodel.cachefly.net/downloads/instructions/M4209ADPTAC.pdf
The speedometer currently read like 80mph when the GPS says 20mph.
Any recommendations would be GREATLY appreciated.
