Cylinder pressure has many other factors, the #pounds of boost is somewhat insignificant. Ignition timing, IAT, barometric pressure, altitude, etc are all influences...timing especially.

I totally agree that e.g 17 PSI boost can be a lot more dangerous than 19 PSI depending on other factors than the actual boost. What I'm trying to do is to kill the myth that there is a distinct border between safe operation and catastrophe at e.g. about 17 PSI, and based on my experience to claim boost above this point may be reasonable safe if properly orchestrated by the tune and supporting mods.
