weird.... post is gone..
I own a 2009 XLT 4wd SC 189000k, I currently have a BullyDog GT Gas tuner
I have a choice to swap a friend for his X4, he no longer has the truck it too was a ford.
My question is, does anyone have the X4 on a 4.6l ?, and if so what all will it allow me to do?
The BD only let me switch 3 options, but other trucks Can adjust wY more.. is thete a reason? And If i finally ever add my long tube headers and high flo cats will the X4 help with those?
If I can get any nfo or help by tomarrow evening that would be awesomw...
Tanks yall
