I own a 06 f150 5.4L great truck but lacking in power want to know if chipping makes a noticeable differents in power before i buy one and install it

a chip will give you 15-35hp. it's not a huge difference, but it's best used in conjuction with other mods. and a quality chip will cost $300-$400.

if you want a ~50-60hp difference, then a chip, new air intake and cat-back exhaust is a good starting combination. it'll give better sound, better intake/exhaust flow and will unleash a bit of extra power.
