I understand there is a tool Lingenfelter makes in order to unlock the factory limit. I read it in GMHTP I think. I think that was ADM's 'V pulley, intake, tuning article.

If you go to a reputable shop, like one of our Sponsors, you'll be just fine. You get what you pay for, though. I definately wouldn't go anywhere that doesn't do a lot of tuning on your specific car.
