Give Mark at MD Weaver Saab a call (he seemingly doesn't have a website) at (717) 661-7331 and see if he may be able to help you out. He's in Leola and is super straight forward and doesn't BS you, I borderline have to convince him to do work on my car. Swedish Motors in Marietta could probably do it but they are $$$, if you sweet talked Kelly Cadillac they could probably do it too, but again, $$$.
I am in Lancaster and have a Chinese Tech2 (and Candi?) that you could use if you're up for trying to program it yourself, but I have zero experience with 9-3SS or XWD so would be of no help.
