Pete @ Performance dyno is in Loudin NH, about 75min from you.
Great guy, great tuner. Guys come from all over to bring their cars up there, and I have mine tuned by him as well. Also, since dyno tuning is a side business, he is extremely inexpensive.
Chris @ MPE Racing is in Tounton MA, about 60min away.
Same as Pete, great guy, great tuner. A buddy of mine has his car built there, and Chris is OCD when it comes to the details. He spent 20+ hours tuning the car before it was built, with just hotrods and a whipple kit, to make it perfect.
Now, I'm sure Pete does the same thing, otherwise people wouldnt come so far to get their cars tuned there, but since I don't have a crazy combo, I can't comment. I've seen some of the cars he has tuned there on dyno days, and talked to the owners, and they are all beyond satisfied.
