Mine is pretty accurate- to within half an MPG. My buddies truck is an 04.5 auto w/ 3.73 and his is right out to lunch.

Mine is an 05 and the diff from the overhead shows about 4 miles higher than hand calc.
Supposedly there is a flash to correct the overhead bit Im not sure.

Mine is within 1mpg. I was getting 17.1 actual mpg @ 77mph (2150 rpm). The overhead was showing 16.4. Not too bad off I dont think.

My 05 is off also, 2-3mpg, I'm getting 13-14, its saying 17-18. I had the flash done and its still off. I usually hand calculate anyway, safer bet.

On my 04.5, it said 23 mpg, filled up and it was 18.5mpg. 18.5 is all I can get out of it too. kinda sucks.
