Fastlane Motorsports in Benson N.C. installed a new Roush tvs2300 supercharger in my truck last week. I have the limited lariat f150 with the 6.2l v8. Factory numbers 340rwhp (411hp). After install and dyno it is now producing 523rwhp (633hp at the crank). The guys at Fastlane did an amazing job. Fastlane Motorsports
Here is a link to the dyno video.
