Stillen in Costa Mesa, CA can help you.
http://www.stillen.com/ it's a 45min drive for me, but for you unfortunately, you're going to have to remove your ECU and ship it out to them. it's $400 for a reflash and they will remap your air/fuel curve and increase your redline by a few hundred RPMs, to give the car a few more ponies. i'm planning on doing it very soon.
