The computer controlled read out on these trucks is useless.
The only way to know your mileage is to check manually. If he finds better mileage in CO than TX...then there's something very wrong...it should be the other way round.
I don't have enough knowledge of the computer controls on the newer electronic Cummins to know if the O2 sensor could have that effect but I'm having dinner with the manager of PDR tonight...I'll ask him.
