[impala04ss]

I live in the Boston, Ma area. Does anyone know where I bring my 04 Impala SS to get chipped via obd2 port. I know a product called Hypertech sells them and the only good thing is since I own it I can always reset it to original defaults when I bring my vehicle to my dealership to get warranty work on it. But I am not sure if I want to spend the 300-400$ to do so...any idea's?

And I know I can get my PCM reprogrammed but I don't really want to screw around with the motherboard.
