Are there any shops around that do open source tuning? I've decided I should start looking for one because even after a few weeks of researching I still don't feel comfortable enough to try it.

I drive a 2006 2.5i with Borla Headers, STi catback, and a hybrid intake. I've been considering cam regrinds and this is when I would really want to get a tune.

So if anybody has any ideas on where I should go, I'm all ears.
