In this picture we can see that engine load as measured by the PCM is 39.28. Again, this is roughly a 20% reduction from what was measured when the truck had 3.55 gears/33" tires.

All measurements were taken using the following OBDII scan tool:
ScanTool 425801 OBDLink SX USB

and using the following software:
ForScan Lite for Android.

While engine load is significantly reduced, unfortunately so is the gas mileage in town. City driving nets me about 11.2 Mpg so far, while the route I take to and from work remains at 12.9 Mpg.
