I've heard of two places, JS Dyno and TPG Tuning. It looks like JS Dyno might be closed, based off of their facebook. I haven't looked into either of them yet, but there seems to be more info for TPG Tuning. If you talk to either of them, let me know how it goes. I'm, also, looking to have work done.
