I have a 2010 F350 5.4. pretty much just the leveling kit and 35-12.5 and i am averaging 12.5 mpg. I was thinking of getting the superchip 1685 and a CAI. How much gain can i see in mpg and hp. Just trying to justify spending the money and seeing if i will be happy with the results. Any info is greatly appreciated!
