I have a 2010 with the crappy 3.8. I am running 35" BFG mudders with the teraflex 2.5" lift. I do not do any highways, only because of small town. I get 14.5/15 mpg all city mileage. After using the flashpac everything shifts better and it feels ok.
2 Great Danes the black one is 3yrs and the brown is 1yr and then my 9yr. old boxer
My 5yr old mare
13 year old thoroughbred
2 cats and a dead parrot buried by the barn.
