EFI Will be 45 minutes or so, from Milford. They are a great shop, and they do mechanical work in addition to tuning. I've gone there a few times for mechanical work and have never been sorry. They are well regarded around these parts! They are a bit expensive, depending on who you ask.
However, AZP Is also a great shop. I have driven to New Jersey before, to have them do the majority of my build. Excellent group of guys, and fantastic workmanship.
