I am new to this site and this subject matter but would appreciate some help. I have 2004 FX4 w/5.4 and am looking at the G-Force chip I saw advertised here. I am looking for ways to increase the fuel mileage and wonder if anyone here has had any experience with it?

 

DON'T BUY IT.......
It's junk......

just because it's advertised doesn't mean it's good....
