2006 C6 CEL Code P0420

Hello all,
About 4 months ago got myself a nice 2006 C6 ......... Anyways, Ive put about 4K miles on it, and I love the car...but just got a dreaded CEL .... car runs fine, no signs of problems.

So I take car to Autozone and the do free scan, get 1 code; P0420

So I research and find that there is a TSB for 2007-2009 C6's that involves reflashing the PCM to get rid of this (TSB 09-06-04-011A).

So my question: Is there a TSB for 2006's that tackles this situation?

Im about to take car into stealership but I want to be prepared with all possible ammo so that they don't pull a fast one on me!
