hows it going ladies and gents... I have a 2006 for f-150 4.6... very unhappy with the power in the truck and am looking to make it faster and hopefully not void the factory warranty... Any help would be appreciated!!! thanks
Several (I recommend SCT-Superchips) programmers can let you tune your mapping for stock and light mod engines. Having a 4.6L you have a ton of bolt ons you can search for on the net.
