I have done a few Roush supercharger kits on the 5.4's. The kits are extremely nice and come with very detailed instructions. There was not a single piece in the kit that had to be modified and the fitment was perfect.
You do not need to change injectors, actually the only thing that needed to be done was to have the PCM re-flashed (which is included in the kit, box and shipping included), and different spark plugs installed (also included). Otherwise the kits can easily be installed in a day. The kits I have done were non-intercooled, and were advertised as a 100 hp gain. Gotta love the sound too.

Dont take my word on this, but i asked a mechanic once, and he said the prochargers arent the best for our engines, didnt give any real reasons except that they didnt work right... just food for thought.
I have looked into them as well, and a Roush is a good one, I havent done one yet because of the $$ involved... so if anyone feels like donating...   haha yeah didnt think so

Well after furthur research, it seems that the majority of people love the Whipple 2.3 Twin Screw.
It supposidly puts out the most power and has a sweet updated design. It is also a little bit cheaper, selling on ebay for roughly 3500 bucks =)
