I'm not really familiar with the Ultragauge, but I believe %Load is an estimate of the amount of torque your engine is producing, divided by the max torque at that rpm. Torque is basicaly propostional to fueling. On a gas engine fueling is proportial to air flow and air flow is proportional to intake presssure. On a diesel, the ECM commands the fueling directly.
As far as the usefulness goes, %Load will basically tell you where you are vertically on a BSFC map (0% is at the bottom, 50% is halfway up, etc).
