I was doing some checking , and it appears that my 04 does not have the instantaneous reading for MPG like my fathers 01 has. It will give avg, and when you reset it it appears to be instantaneous,but at that point it would have to be instantaneous. My fathers 01 manual lists the instantaneous feature,and truck has it, but my O4 manual doesnt. Is this Just me , or did DC do away with this feature. I thought I ordered more options than my fathers 01 had, but it appears that theyve stripped these trucks to much to cut costs, so your ending up with less.
