Anyway, your approach is clearly the right one. At the "lugging" speed of 45 mph, which gear uses more gas? And, if the tune locked you into the "higher gas use" gear at that constant speed, then it's not the right one.
But, if you are accelerating, and lugging momentarily, do you get out of the high gas use region faster and with less fuel than if you downshift, then upshift again?Only controlled experimentation will tell. In my position, driveability reins over economy....mostly because people in my neck of the woods USE their trucks.
