Performance shops in PA

JD's is just outside philly and Kaufmanns is a little further but worth the drive I hear...then you have Radical Racing in Atco( next to the track) a few guys on here use them.

i'm sure a quick google will pop up some #'s and addresses for you.
 
Kauffman's is without a doubt the most user friendly shop to deal with. Their prices are more than fair,the work is all quality. I went there after getting a hack job from LaRocca's. Kauffmans retuned,got my Stangs drivability & reliability back to normal.(and added plenty of HP)..Call them and tell them what you are interested in doing. The ride is simple(2 roads) 125m & worth it. Good luck.

JD's has a good reputation...but they are 4 star $$$$
 
Another vote for kauffmanns

The Guys over at kauffmanns are dome of the best that i've ever had work done. and he can do anything from mild to wild. Going to have him retune my kb setup.
