There's a thread comparing the two. Apparantly though, the powerworks numbers are artificially low, and Focus Fanatic isn't a reliable magazine for dyno information.
That being said, for the procharger kit, you can get a custom tuned chip, race header (kamikaze work best for SC applications because they're the only 2.5" race header available), matching flex and exhaust. Throttle body, intake manifold, huge FMIC, big boost kit, aftermarket MAF. You also might want to look at FI/SC specific cams and cam gears.
The Powerworks list would look very similar, custom tuning, larger FMIC, larger injectors, aftermarket MAF, big boost kit, header/flex/exhaust, 70mm throttle body, and the cams/gears.
