Gentleman i have 4.10s and they are killing me. Just wondering what others have done to increase their mileage. 05 dodge dually 4x4 with a 6 speed and 4.10s. Thinking about putting some 35s on it with bigger injectors and a smarty. Currently just have straight pipe and CAI. I get 16mpg wether i dog it or baby it 17to has been the best. 600 miles on a tank damn near all highway.
