We have had our TBSS for 19 months now and lurked for many months. It is an 08 RWD and black. Already used the site to diagnose and repair ingition switch issue, big thanks for that I would have never figured it out. Also have an Silverado SS and a member on the SSS website as well (great guys there too). TBSS is her SSS is mine. Both are stock for now. The SSS will get modded first, I'm tired of getting beat!
