After market throttle bodys
Just wondering if there is really a difference between an aftermarket throttle body and the stock throttle body. Im not sure of the size of the stock throttle body. I have a CAI, after market mass air sensor, throttle body spacer, and soon to have a custome tuner and headers and true dual exhaust in my 2010 fx4 5.4l. Thanks everyone.

Total area: 31.15 sq.in with 80 mm; 35.17 sq.in with 85 mm body. Whoever says 5 mm doesn't make a difference doesn't know how to count! See this calculator (you'll have to convert MM into inches by dividing 80 and 85 by 25.4)

I put a BBK throttle body in my 99 Ranger 4.0L and got noticeable improvements in throttle response with no impact on fuel mileage. Caveat: when I pre-installation checked the operation on the first one I got, the throttle had a serious sticking problem. Sent it back and the next one was flawless.

On my 2011 truck the stock body is 80 mm in diameter. I got a replacement from BBK via Autoanything. Theirs is 85 mm. It was plug and play installation. I noticed the difference right away. 5 mm difference in diameter creates FOUR SQUARE INCHES (!) of additional opening for the air to get in.

I shoot vids and post 'em as I make changes to my Ford. I just got word from the gear shop the 3.73 diffs are in, so once I'm back from this Arizona trip in my big truck, I"m going to load the SCT tune from 5 Star and .. go for a ride with the camcorder
RE: the BBK
I think all these small changes add up.. The throttle body isn't cheap but if it's bigger than the stock one in your truck, I'd say it's worth it.
