I find it hard to believe that you can get better fuel economy with your foot as oppose to CC. It may be under high loading and mountainous terrain CC could easily have trouble managing power better than the Mark I brain/foot control. PID controllers can only do so well, especially when the feed forward is not available to CC.
However, outside of those conditions CC has got to be able to manage MPG better than the foot. I will certainly have more data about this later this summer. On the hills the Dmax/Allison/CC seems to work very well together. This might be totally different at higher altitudes and much longer grades.
I would say with a gasser, I would not be surprised if that were true. The gasser is going to spin up/shed a lot more under high load conditions. The engine is going to rev up on the hills and then shed crossing the peak and then drop very low on the downhill side. I know my Taco did that a lot in New Mexico.
