We're our own performance shop. There really aren't any good shops in CT I'd trust my 7.3 to.
We've got a club of Seven Three Powerstroke owners in the north east area known as North East Seven Threes aka: NEST
We've done just about everything imaginable to the 99-03 7.3s aside from rebuilding a transmission. We've done injectors, turbos, hpops, up-pipes, intercoolers, trans coolers, valve bodies, etc.
It's really no big deal. Just order your parts from Clay at Riffraff and come out to a meet you'll learn a lot and you'll know how to fix stuff yourself if it breaks.
Our next meet is in East haven, CT on May 22nd we're doing injectors and a turbo on a lifted 7.3 if you're interested in coming let me know and I'll PM you the street address and my cell # if you want/need it.
