I got an 04 f150 5.4L
just K&N CAI and BORLA exhaust(boy I am proud of that)
Goal on those were to save money on gas, and to beat my buddy's Chevy 2500HD >=)
Turned out Borla didn't help at all on gas, and the K&N actually took away gas mileage.
Asked WTF was going on from the boys on f150forum, and they told me I needed a custom tune with a Gryphon from you guys.
I think as soon as I get a custom I will attempt my buddy on the strip.
So, this is why I am here.
Hope to learn a lot from you guys
