very poor MPG IMO... possible causes
So i bought this supercrew short bed 4X4 because it figured id get similar MPG as my 99 extended cab long bed. Boy was i wrong. went on a trip to Corpus Christi from san antonio and averaged about 14 MPG highway!!!
compared to the other truck which consistently has given me 19-20 on the same trip.
tires are toyo- open country, suspension is all stock.
the truck has AFE stage 2 intake and was on bully dog street tune, same as the other truck.
the only difference ive noticed is even after alignment this truck shakes a bit when you get to almost 40 mph, and slowly the vibration goes away at higher speeds. also at idle this truck sounds a bit lopey at times, not smooth like the other truck...
any help? thinking about selling this truck already.
