Hi everyone! Just a quick introduction! I think I may have been a member here quite a few years ago when I had my little RCSB with the LS6 in it. Anyways I'm Shaun, I drive a 2007 Silverado CCSB 4x4 with the 5.3L. Pretty close to stock, other than a Blackbear tune, K&N cold air intake and MBRP catback exhaust. Putting a cam in it this weekend! Nice to be here and share some knowledge and also learn from you guys and gals!
