I have a new f-150 with the new 3.5 ecoboost engine. It runs great, has plenty of power. I'm not getting the 22 mile to the galon like they advertised. Anyone else having this proubem? I just added a k+n air filter, hope this will help. I had ford check it out and the computer says 19 mile to the galon is in speck so they will not do anything... I like the way it runs but i want the 22 mile to the galon also...
