You can get them lots cheaper online. My understanding is that it's just a plug-in module that needs no tuning.

I think you might be thinking of something else. The turbo upgrade kit is a module that needs to be installed and then the ECU needs to be reprogrammed and tuned for the added HP, etc.
I believe there is just a performance chip but I'm not positive if it's a GM part and may void the warranty.
