Can I do any performance mods to a 4.7 flex 2007

I appologize for the late response... been working on the new website... forgot to check on the forum.

In short. Yes. All the mods you can do for the Non FLEX 4.7L you can do to your FLEX 4.7L...

what exactly are your goals? MPG, increased Towing ability, or just wanting more power?
