I'd assume you're willing to ship the car since you were pondering Livernois and Forza. If so there are a lot of good shops out there.
If you're trying to stay as local as possible then there are still some good options.
You cant go wrong with HHP in DE. There is also True Street Perf/Hemituner in NY, and Ripatuned in NJ.
I only have experience with HHP & Ripatuned (no affiliations BTW).
Good to see another fellow NJer on the board.
