It is much more common to see one supercharged, using a roots style or whipple style supercharger. I recommend going this way if you want forced induction.
Speaking in general terms, a turbo'd 5.4L in a Super Duty probably wouldn't work well. You want more power on the low end of the torque curve. Superchargers will do that for you. Turbo's tend to increase power on the opposite end of the power band.
There are enough companies making kits for Mustangs and F-150s (4.6L and 5.4L) that you should be able to adapt one fairly easily to an F-250. You might have to also include a custom tune to handle the transmission, but you'd probably want that anyway.

I've seen one done, but it was done with racing in mind though.

One of the best things about diesel compared to a gasser is that turbos cost less and gain a whole lot more, but I'm going off topic here. Carry on.

A guy that lived across from my mom had a f150 excab 4x4 with the 5.4 he did the tuning on his laptop and got it to like 505hp and 495lbs tq. it was right at the 500 mark tq and hp. It would out run most of the lightnings around here and cameros. Even took a few vettes. He built the kit him self and it did run pretty good. He bought a bumper pull trailer and sold the truck and got a 06 f250 psd.

Hmmmm I don't think you understand. He made those number at the rear wheels which means he probably gain over 120 hp and 150lbs of tq. I think spending 5k for that is worth it.

Yeah, a turbo is more efficient overall, since it is powered by waste energy. It does bog the engine down a little bit. The trick is to get a turbo that spools quickly. For this type of project you actually need twin turbos. One off each manifold. More costly, but turbos need to be up close by the manifold, but since you need cats on each bank, there would be too many complications to have a single larger turbo. Twin turbos will typically spool faster.
It would be a big project, expect to spend several grand. You will also want an intercooler. However, the results would be very quick and it would tow well. One thing you should take into account with either a turbo or supercharger, is that the trans is not intended to take that kind of power, so you may want to look into some modest upgrades in the transmission namely a tougher torque converter, and a shift kit.

Sts makes a nice kit. It is a remote mount. It is said that there is little lag and since the turbo is farther away a ic is not needed. Biggest thing though is to watch how much compression you have. Might lead to a new engine if you get to crazy.
