I just put a GT bullydog 3 tuner on my Ecoboost but it's compatible for the 5.4 too.. I've gone up about 30 hp and 30 torque, it helps a lot with the bigger tires on my lift. .. It's about $469 and well worth, sits on the dash and has a touch screen, can set whatever gauges you want on it for temperature, speed, boost, fuel economy whatever! Also can do performance testing such as time a 0-60 , and also took the limiter off so even though it's not a good idea on my mud terrains my truck is capable of 150 mph now. Well worth the money IMO.

GTFO!!!
90% of CAIs are the same so the tunes should work fine. The only ones that would be different are a Ram Air intake in which you're forcing more air than normal.
