I have a '99 F-150, 5.4 liter. I was wondering what a Superchip can do for me? I dont know anything about them, so if someone could help me with some info ie; install, quality,and performance.
Is there a good brand out on the market? Will this hurt my warranty?

 

You would probably get a better response under the chip forum. You can also go to the top of the page and hit the search button. There is a ton of info on this subject.
