OBC calibration

About a month ago I installed a four stalk switch and activated the OBC. All went well and everything works. Last weekend my wife and I drove from phoenix to albaquerque for the balloon festival, 80-85 mph the whole way to and from and my average MPH said 45 and my mpg said 23, when I cyphered the gallons into miles I came up with 26.9. Is this inaccuracy normal, am I being too anul or is there a way to do a reset/calibrate on the OBC? The miles to empty is very accurate I feel.
Thanks in advance,
