I have a 2005 4x4 f150 with the 5.4 liter v8. I just put the kit on 2 days ago. It went on smoothly I had my father help me and it took us about 2 hours to do it. I have the edge programmer and flow master so I some power already. But you can tell the difference when you put your foot down on the throttle. The engine is a bit louder when you putting your foot down on the throttle and the get up and go is faster. I haven't drove it enough to know if the gas mileage is better. Also one thing I notice is no whistle noise when the truck is idling and the truck isn't any louder when its idling.
