Not too many people on here from PA. The best place to check and ask would Tristatetuners.com :Click Here. It is a big forum and they have basically checked everyone out in the Central/Eastern PA area.
Rt tuning, psi performance ar both in lansdale and have a dyno inhouse. If you want a cheaper alturnitive my buddys dyno is in storage but he can street tune for you.
Ill be running a 10:1 turbo setup on my f23. As of right now im just trying to get in touch with a few guys and see what they are pricing for dyno and tunes
These guys are one of the best tuners on the east coast and are in Carlisle, PA. Prices are fair not sure how close you are or what you need done though.
