Question
Barony
I posted about a month ago about the 4.6 v. 5.4 F150. I ended up getting a 2005 5.4 that to date, gets about 14 mpg. I realize that running the AC doesn't help, but it's been mostly highway miles and a little driving in town. I had the boat out yesterday and got 13 on that tank. My question is can the dealership modify the computer so I can squeeze a few more miles out of a gallon or is it just the nature of the beast?
