tuning 2011 6.2 Vortec
I bought a 2011 Sierra 4x4 with the 6.2 Vortec a year ago and put dual exhause and a Banks CAI on her. Now looking to play with the computer a bit. A couple of my buddies tell me about this guy "JP" her in the summerville/Charleston area that is supposed to be legit. Anyone know who this is and how I can get ahold of him? Last they knew he was floating around not working out of any specific speed shop. Thanks for the help.
