Yup. "Real time" on a heavy pickup appears to make the gauge a necessity.
I don't have a Scangauge, so I don't have an instananeous read-out of MPG, just the average trip mpg from the lie-o-meter. What I do is reset the lie-o-meter at the beginning of my trip.

Here's two tips for using the lie-o-meter:
First, if you have a regular route (like commuting) what you can do it set "checkpoints", try different techniques and see how they affect your trip mileage up to that point. For example, I check my lie-o-meter at the bottom of the first "hill" out of town. On a good day I'm at about 30 mpg, on a bad day (like today) it was 25 mpg. Obviously it's not an exact science and there's a lot of variablity with weather, etc. but it will give you an idea of how well you're doing. You can try different techniques and see what the outcome is. From my experience what will happen is one day, you'll get it right and will suprise yourself at how well you did--then it's a matter of figuring out what made the difference and repeating it.

Second, when learning to P&G just compare your avg mpg at the bottom (or top) of each P&G. When pulsing your avg mpg will obviously go down, but note whether the avg mpg at the end of this glide is better than it was at the end of the last glide.
