No idle, running horizontal through the map. water temp sensor?
So my power fc isnt holding idle, i have to initialize it every time i do a cold start, the boost readings are off, and its running pretty much just a horizontal line across rows P09 , P10, or P11. Could this be due to my water temp sensor reading in the commander being blank, throwing off corrections?

There is no check valve, there is a filter that flows in both directions. There is an arrow that should be pointing towards the UIM. Try charging vacuum sources, the fact that it is reading a signal implies that the sensor is not bad, otherwise it would default the max boost.

Idle is working now. That seemed to be unrelated, perhaps the powerfc just needed a REALLY long time to learn the idle.
The map problem persists though. I have tried several different vacuum sources, flipping the filter, but its still running an almost entirely horizontal line in ghost map trace.
It will start out at P09, and get into P10/P11 if I get on it and build some boost. I've tried swapping map sensors with the same results. On the sensor screen, PIM is reading 2.67v with the engine off.
It will get over 3v when i start getting into boost, and very slowly drop back down in .01v increments

So I changed the vacuum source once more and the voltage was reading better, 1.XXV. I tried removing the filter for a minute too, and the map trace seemed to be moving around as it should. Going to pick up a replacement filter and give that a shot.
