I have an 07 LBZ with 200K on it and completely stock. Has anyone had their truck flashed at GM with the current PCM programming they have for these trucks? Are they still updated by GM for better performance/efficiency parameters? If you have had this done did you notice any difference in your truck? Just curious if this a thing or just a waste of time and money.

I have a 2008 and it has had no updates since 2010. It takes someone with SPS access to see what your truck has and what the most current programming is. I suspect that if you are NOT having any problems, you won't see any difference.
