Re: 5.3 PCM
No stock PCM will directly work, all need a reflash to turn off vats and other things. Since its being reflashed, what tune is in there from the start makes no difference
I use cheap s10/van pcms with the 4.3 v6 for that very reason

Re: 5.3 PCM
VATS is part of the security in the pcm and has to be disabled b4 it will start, if the vats is turned off the car will run but may run poorly until you get some kind of tune on it for your application. If you don't have a place local you can send it off and have the VATS disabled and a base tune put on it, they will want to know all the details of your build to get something to get yya started.
