Use a steady speed when driving and use cruise when I can. Been getting about 15 lately but not a lot of highway driving and been playing in the snow.

2002 Wrangler Sport with 4" lift, 33" x 12.50's, and the 4.0 liter on stock Dana 30 and Dana 35 with 3.07 gears... I get 10 to 11 mpg. Working on scraping up the cash to go to a better rear end with 4.56 gears all around for better mpg.

But if i was getting 15mpg with them and then 9mpg with them should it return to the same as the only changing variable is the air intake?
