Just needed to get a quick opinion from people out there. I have a '06 LBZ CC/SB with 58K miles on it and it just threw the P0676 glow plug circuit code on Chritmas Eve, merry Christmas to me... I have her scheduled to go into the shop tomorrow and wondering if I should pull the six gun tuner out of it quick and try to fly under the radar if the glow plugs come up as something that can be warranted, or should I save my time and just suck it up when it comes time to pay the bill, cause any tech would know something is up when they see the EGT probe drilled into the manifold right next to the #6 glowplug when they work on it anyway... Let me know your thoughts.

According to the Service Manager at my dealer -a decent one IMO, GM requires a Snap Shot of the ECM calibration for any "engine" related warranty claim. We had this discussion when I was picking up my 06 from having all 8 GP replaced.

Glow Plugs are only $15 at Oreily for AC Delco, if you don't want to worry about screwin your warranty up. Could just do it yourself.
