PCV valve on the passenger side valve cover possibly bad? The driver's side is not a pcv fyi.

Pcv valve and pipe is new on the passenger side

I'd continue to check the easy stuff, like the vacuum system, check valves, plastic fittings that night be broken or loose, and the pump behind the headlight. When those things fail they might affect intake pressure differently when cold, warm, or at idle and partial throttle. If you start it up cold and drive without any warmup time do you have brake pressure?

The vacuum pump behind the driver side is going out but everything iv heard about the pump says it is essentially for the brake system

"getting a weird hum like noise at start up and while driving that seems to be connected to throttle position while driving, noise seems to be resonating from the intake manifold. I’m having weird idle issues, low idle issues, no boost and extremely low power while driving" good description of the intake leaking boost. KM

That is what I’m assuming, I just ordered new intake manifold gaskets. Hopefully this will take care of the issue

And no codes? All the old View attachment 195956
plugs conditions looked similar? BTW, that was my 2012 throttle body at 175XXX miles. Cleaned up easily, didn't find any evidence of grit or dirt getting by the air filter. Not bad,for a truck that lives in the Hi Dez.

Plugs looked similar but definitely needed replaced. The driver valve cover was leaking oil out of the cover and into the spark plug tubes so I replaced the whole cover, new boots and seals on the coils since I didn’t have a misfire, and new plugs gapped to .30

All hoses that also go to the cold charge pipe are intact and in good condition?

All the silicone boots are in good shape, and I tightened all the clamps up while I was checking on them.
