Have cleaned the MAS with appropriate cleaner and still no change.

Will fill up tank and run to North Pole and back to see how the mileage is affected.

I do understand that long idle times do affect MPG. I will try to find an idle per gallon average and see what that number looks like.

The only thing that I can see is if the truck originally had a program placed on it that is still on the truck and eating my gas mileage. However I can't seem to find anything on the truck that would reinforce this idea. I really am at a loss trying to figure this one out.

Thanks for the help guys.
