I plan to buy one of those XCAL2 from B@M@ along with some 3.73 fordracinggears. Does anyone suggest something other than this for my first two mods? Is there something I could get for pretty cheap as a third mod, I have considered shorty headers. I plan to install them all at once. Thanks

Exahust will give your least bang foryour buck, those are 2 best bang for the buck but make sure you have a very good shop install the gears.

 

dont buy shorties your wasting your time and money

 

+1 on the shorties I've been told the same thing.

Who are you planning to have do the work?

 

A Ford Dealership will do the install. My friend is a technician(mechanic)for Ford and he says if I bring my car to his dealership he will install the gears for free and give me an OEM certification so I will still have full warranty coverage.

 

Does anyone have an estimage of how many MPG I will lose after these two mods are installed?

 

gears you'll lose a couple mpg but the tune/intake should compensate for that
