I have an 03 F-150 STX 4.6 liter V-8 w/ 39000 miles Supercab stepside all stock
with I think 308 gears (80 MPH tach reads 2 gran.) Any ways was looking for supercharger or turbo.
Can any one suggest some mods to help out performance with my truck? That maybe wont kill my pocket book as much as a supercharger? (which is hard enough to find for a 2 value 4.6 liter V-8)
I've heard about headers and some good flow exhaust that really helps and is not that expensive, also ive heard about messing with the computer to give you different settings.
