If you think your 6.0 drinks a lot now, just wait until you get your Black Bear tune!!

Oh, the tune will give you the ability to get better mileage, but your foot won't want it to. You will have so much fun with your new found power that you will want to use it

Not in the HD's. The 6sp is geared differently. I think most of them still come 3.73s or 4.10s
