Because I've owned 3 gm trucks with the dic and they have all been off by small or large amounts. Usually they get messed up due to a tune but I'd rather do the math myself, I really don't like knowing when I get 2.0mpg with my foot down either.why does everyone say the DIC is not accurate, most of the time peoples math is calculated wrong. do you calculate acceleration from stop go traffic, of passing someone on a two lane highway or when you coast down a hill, well the DIC does. i have a 2003 GMC Envoy fully loaded and its DIC is usually 2 to 3 mpg short of what i calculate.
