Low MPG
Hey everybody... I have an LB7 Duramax with about 130,000 miles... I don't really know what MPG's i was getting before some upgrades, but i'm really not getting good MPG now...
I have 35" tires, 8" lift, and Superchips tuner on Mileage XS setting... I'm getting around 12-14 MPG... I would think it should be around 17-20... Any thoughts???
I've checked for bad break calipers and all my fluids... Just FYI, sometimes i do pull away from gassers at red lights
