Thinking about buying an Edge for my 05 F150

[Barrett]

Hey y'all, first time post here. I'm sorry if I missed some thread that could have helped me before posting, but I tried searching with no success.

I drive a 2005 2wd f150 (5.4). Recently I've gotten back on the idea of possibly getting a programmer for my truck. To save myself a chunk of money (Broke college student), I'm thinking about getting a used edge if I can find one at the right price. And then later look more into getting it converted to a gryphon and custom tuned by PHP.

My truck has a couple mods, I'm over on f150online with the same username. Performance wise on my truck I have:
Dual borla pro xs mufflers
Gotts mod
K&N drop in

Will running an edge with canned tunes be a bad idea for any reason? I'm hoping to get some power to help my 3.55 gears turn my 35" toyo mt's, and crossing my fingers for some mpg help if I stay driving the same. I only get about 11.5 or so city at the moment.

Thanks for any help y'all can provide, I've searched a good bit on f150online, but could really use some direct advice.

Thanks y'all,
-Barrett
