Thanks for the input regarding the speedo. After changing my tires my wife was using the truck and noticed a big difference from the speed trap signs (digital readouts). Then I had the opportunity to drive a "newer" rig and the trannyshifts felt totally different. After driving a while I started noticing a drop in mpg.

This gauge is controlled by the instrument cluster circuit board based upon the cluster programming and electronic messages received by the cluster from the Powertrain Control Module (PCM) over the Chrysler Collision Detection (CCD) data bus.
The Smarty can also recalibrate it for Tire Size
