dem shoes......
I'm not sure what my new 5.4 F150 FX4 will get...I'm hoping 13-14mpg It has the factory 17's on it now...my plans are updating to 18's and using the 18" all terrains that came on my Wrangler....so hopefully it won't change much .....I have a new S331 Saleen exhaust ordered for it...so maybe by next week it will be installed...and I'm hoping it will help some...on gas milage
