There is a forum on the web site and in it I found an Excel spreadsheet and other info. For the protocol I could only find info up to 2002 for Silverado's however I would make a strong assumption their all the same.

<TD bgColor=#cc99ff>Silverado</TD>
<TD bgColor=#cc99ff>2002</TD>

I'm still looking for more info on support for our trucks. This software would be great for laptop owners as it would be much cheaper then buying a handheld tuner.
