Wave tuning is an annual discussion on SpeedTalk (basically every time a person learns about the topic): https://www.google.com/search?safe=o...iz.ZuQNfHAfYEU
Here some stuff on plenum volume: https://www.google.com/search?safe=o...iz.vdeqkY7v8Cc
The problem this site inherently faces with intake manifolds is the restriction the 4th Gen F-body chassis proposes. Those of us without those self-imposed limitations have far greater options and it tends to matter less.
I would argue that in lieu of volume you should consider optimizing what you do have in order to maximize your chosen intake's flow potential by using things like porting, radius rods, epoxy, better pre-throttle body tubing/filters, etc, etc, etc.

My understanding is flow bench testing won't show any increase in airflow removing the post. The air generally moves around the sides of the intake instead of straight down the middle where the posts were located. On the dyno having the posts gone might show a slight benefit.
