I'm a proud owner of a 2000 f-150 4x4 with a 5.4 under the hood. i just bolted on a k&n intake system. i moved to the 285 bfg all terrians. i got my flowmasters cut off about a year ago cuz they weren't load enough and now i have straight pipes behind the cats. now i'm lookin for a performance programmer. i've looked at hypertech and edge and i'm not sure which one is the best. any suggestions would be greatly appreciated.
There is no such thing as best. Either of those or a superchips, SCT, Sniper, ect. are good choices. Personally, I like the sniper setup. It has all of the options I want and can do most things I need done.
Figure out what you need; tire size/gear ratio correction, power increase, ect. Then pick the one that fulfills your needs and you like the best. Read the sales pitches and see if one tickles you just right. If that doesn't work, go to a speed shop and ask them what they like.
