Reprogramming Canadian car to be configured as US

Well this came up in the FOB programming thread and I figured I would bring it to the front in hopes that more people would see it that may normally ignore the FOB thread(s)

I have a Canadian spec car. It has now been imported into the US. Being Canadian specd that means I cannot program fobs among other things. It has been mentioned that I should be able to go to a dealer that has a Tech2 and they can reconfigure it as a US car. I just called one dealer and it was like I was speaking martian to him. "ahh I don't think that is possible or where to even look" and that is one of the big chevy dealer's in the area. /facepalm..

Does anyone have any experience or hard data on that? Even better would be info on where in the tech 2 they would need to go in it to do this..
