Well I finally got around to changing the speedometer gear on truck.
I had the stock speedo gear with ProComp 33/12.5x15 Xterrains and had the truck calibrated by AAA. You can see the 2-9 mph variance as well as the actual miles being off by 15% which of course throws off your gas mileage.

I replaced the stock 19 tooth tan gear below...

with the a 17 tooth green gear.

Here's the results. Not perfect but much better.
