I lived in Morris and Hunterdon and off the top of my head I can't really think of anyone up there who would want to get involved with that. The only Ford Performance shop I'd trust in NJ is Kevin Hand @ Wicked Motorsports down in Toms River. He could do the install and tune afterward.
LC3 Performance in Rockway would be my suggestion. They work on pretty much anything but specialize in GM. I know he has done a few supercharger installs on S550's. Great shop with a dyno, tons of bays. It's across from Trend Motor on RT 46.
Late to the party but I am going to be using Performance Ford in East Hanover to do mine in a few weeks. My step son works there (in sales) and was able to get an employee discount on the install.
JDM is a quality shop that I have used in the past for other work
Evolution is outside Philly, they did the Roush on my 2014
