This is my first post and I need some advice for my mods on my F150 4X4 XLT. I'm looking at adding the whole nine w/ engine perf.mods such as Gibson Dual exhaust, electric fan, Gibson headers, superchip, 3.55 rear gear ratio., etc.

I currently have the following basic mods for a start:

AIRAID FIPK injection
BOSCH Platinum +4 plugs
Dual Cat-Back Custom Exhausts w/ stainless steel tips (inexpensive)

I'm looking to start w/ the tires and wheels, and I need some advice on what tire/gear ratio would work the best.

I really like the BFG 285/70R16 Mud Terrians, but I was thinking of going to 305/70R16 or maybe the same size but w/ the Baja claws. I want to make sure that I get the best balance to help with the power increase at the lower end. I figure if I change my gear ratio to 1:3:55 from 1:3:08, I would see enough of a power increase to balance out the difference of the larger tires.

And can anyone recommend the best performance exhaust for power increases? I've heard nothing but excellent reviews about the Gibson dual exhaust.

Of course, after all the engine mods, I would add the superchip at the end so I wouldn't have to change the programming each time I included a new engine mod.

Some of my exterior mods include:

Access tonneau cover
Putnam stainless steel bed rails
Rhino Lining
Altezza taillights
Billet stainless grill
Lund stainless steel bug shield
Stainless steel rocker panels
Stainless steel cab sides and gas tank cover
Clear corner lenses

I'm definitely set at starting w/ the tires and wheels and working from the rear end to the front. Can anyone help me out?
