I work at Delphi Automotive in WI. We have two plants here. One side builds catalytic converters, the other side builds PCM's. GM is making us reprogram the 05 SSR because it is making more HP than the 05 Vette. I am not sure if any of these SSR's got out of the door, but I will surely find out. These would be some interesting trucks. When I find out more, I will post.
