Try Frank at PSI Motorsports. They are a little north of Allentown.
He tuned my 98 Cobra last week. They do a lot of custom work and Dyno Tuning.
I think he is closed this week due to getting married, but you can give him a try at 610-298-2800. tell Him Brian with the Yellow '98 Cobra Vert. sent you.
They specialize in Mod motor stuff and Dave is a great tuner, I've always been happy with there service... The leadttime for Dyno work can be long at times, best to give them a call.
I am surprised the name Jon Lund hasn't been mentioned. Go over to SVTP (MACA section) and his name is all over the place. I haven't been to him (yet) but I hear nothing but incredible things.
I lived in Newtown Grant until I moved down here. Glad to hear you made it over there. Joe is a good guy, problem is he gets busy and sometimes it is tough to get hold of him.
