Best Tuner in New England...???
As per the recommendations by posters Mike/A.W.E. and DAVE W, I visited Marc Fienstein at his shop German Performance Service (GPS). I was not happy with my experience. I would not recommend this shop for anyone looking for suspension work done to their Pcar in the cambridge/boston area. If you want details you can PM me. I'll leave it at that.
I'll 2nd that.
