Great info on this site, thx.
I found a version of the Gotts Mod on here, using the F-250 snorkel tube to to open up the breathing a bit on the F-150.
Very simple 10 mins. Direct fit. Only cost $5.
Throttle response is improved a little and seat of the pants feels a bit stronger on launch. Here are some pics.

Sorry all. I will fix my signature. It is a 2010 with 5.4
