Matt, I would install the system and take it to Livernois. Have a pre-purchased set of 30s on hand *in case* it's determined your out of injector. That way you could get it tuned right, spend less, and not be guessing about the whole issue. If you just went with 30s up front you could up the boost a bit to 7-8psi and just pour the fuel on to help bring the EGTs in line.
BTW: I'm in Howell & Plymouth daily.
