RE: Cm871 bad mpg
Has it been deleted? If so pm me. Your gearing is off with 355 and tall rubbers. It would probably do great on long ass straight roads at 100mph. The harder your engine has to work to move the truck the lower your mpg will be. You immediately need to remove your entire egr system and clean everything if not deleted. Rawze has good videos on doing this properly. And if you dont know anything about the trucks history i would change every pressure sensor on it.... Even the oil pressure sensor. 871s are getting older and pressure sensors actually do wear out.
