2006 GMC 3500 cab and chassis 6.6 stock tune. Getting P0606 codes. from what i can see it needs an GM updated flash. Is that something i could get out of the tune repository? if so how could i find it to know that it is the updated flash??

Good luck getting a response in here. It's a dead forum...........
Normally a P0606 is a PCM failure code. But it seems to be a incomplete programming routine for the diesel pcm.
Are you able to re-flash the pcm back to stock with a Tech2?
