WOW
my 01 excursion has the overhead display.... tha reads mpg. well with the edge juice with attidude on drive mode the overhead display would tell me i would average 19.9 mpg. that was reset when i filled my tank and then 350 miles later. when i filled up again i did the math and i actually only got 17 mpg. so i took the whole edge juice off the truck and the over head readout is back to normal reading about 16.9mpg. this is all withthe same 350 miles i drive for work every week. i filled up and with the truck with no tuning the over head said 16.9 and my actuall calculated mpg is 16.7mpg. so in stock form its pretty accurate. I just prdered a 6 pos chip from PHP so ill put it in there and drive the same 350 miles and report back what it does to the overhead display and the actuall mpg in the 65dd and then ill do a test in the 80dd.
if you get some actuall numbers from the manual calculation way i would be curious to see how much your overhead display or gryphon thingy is off.
