I have. It appears to be accurate. I had the generator turned off, but when I went to check it was on, which I heard that even when not in use can impact the MPG.Your Pcm is miscalculating your mpg by some percentage based on your truck is actually traveling farther than the odometer is giving you credit for. The taller tire has a longer circumference. Your traveling faster than your speedometer too.
Load a GPS app like waze and when it says you are doing 70mph, check your speedometer. Maybe all your mpg are off by say 10%?
