Re: Gear ratio for better fuel econo.

But if I drive 20k to 30k a year it will add up. It was sucking just as much gas when I had the 265's on it. It seems to run almost rich at low rpm 700 to 1200 rpm. I never expected 17 or 18, hoped for 13 to 14 since my 06 hd with a 6.0 got 15 to 16, but 10 is just crazy. My fault for buying it I guess.
