my truck is an 05 super cab short bed, 30 gal tank, i get about 330 miles to a full tank. i brought it to my local dealer, they said my computer was out dated so they rebooted it. i have not seen a notice in my fuel economy. long story short i just am curiouse what you other 6.0 guys are getting to a full tank, and if you have any pointers on why my truck drinks fuel. i also do not blow black smoke no matter what. and i see all these pics of 6.0s blowing it. thanks!
