Coming from 2006 LBZ 2WD CC which consistently got over 20 MPG cruise on highway. Now just purchased 2022 4WD LT CC and cruising at 72 I’m getting 12/13 on DIC. does this seem right? My buddy has L5P 2019 lifted and gets much better. I know truck heavier than my LBZ but 16 years of engine decvelopment and 10 speed transmission this doesn’t seem right. Searching it seems I should be getting 18. Anybody else seeing this?
