Looking on UpRev's website, the only other local tuner would be JE Import Performance:
JE IMPORT PERFORMANCE
8303 D Pulaski Highway
Baltimore, MD 2123
JE Import Performance :: JE Import Performance
(410) 686-5111
If that doesn't work out there's one in Wilmington, DE and after that you'd have to go as far as PA. Of course you could also get an e-tune from UpRev for a lot cheaper. For that, I think they send you the software and then use data collected from your care to make a tune for you and they send you the tune. IIRC it comes with the purchase of the software (~$500) and you get 3 free updates.
