Just a thought, we had an issue with loose cam gears on a few trucks at my old shop. The bolts would come loose, the cam would walk forward and lose contact with the cam sensor.

Sorry you are having issues, you made allot of changes all at once so diagnosing will be difficult.

Got the cam code stopped now it is an Idle code . Put on a new module. Did not help. It is idling at 2200rpm and can not get it down. But it was at 3000.

OK Tune "3" and guess what a new code. PO1336 Still idling high 2500rpm. Checked for air leaks pumped 15psi to it and found no leaks. The truck has been done a mouth and have not put one mile on it. Not Happy right now not at all. Now what do I do?

That code is normal, it's the pcm complaining about needing a ckp relearn, but that's not what's causing the idle issue.
Just to recap and keep those who don't know updated:
pcm 1: tuned what i was supposed to tune for
pcm 2: reloaded same tune just to be sure it wasn't a bad upload
pcm 3: completely different calibration just to be sure it wasn't the cal.

similar issues with all pcm's, so let me know if there's anything else you'd like to try.

What do you think I need to do? Did a pressure test on it today and could find no leaks. What next?

Your high idle sounds like unmetered air entering the engine, or a throttle plate sticking open.

That is what I was thinking but have had no luck finding a leak at all. Put air to it 15psi no luck done every thing I can think of to find a leak but have found none.

I'm not real familiar with the cabled TB's. Do they have an idle air circuit like the F-bodies? If so I'd be looking there along with making sure its closing all the way.

You put 15 psi air to it?? Not sure I understand what you're doing here. Could you explain this a little better?
