Pretty sure I was able to see more flow this way but no one really talks about this or if it's bad for the pump or engine at higher RPM to raise these values. Curious if you have any knowledge to share here.

Both LT1 and LT4 have 130 Degrees max.
I have seen some trucks listed at 132 degrees but I don't know if that is a math problem in the software template.
It is obviously being used to fill the chamber as low side pressure drops we see this number increase and vise versa.
I raise inlet pressure and the duration goes down.
Again we are dealing with
Positive displacement, repeat it in your head
Positive displacement, Hard limited, when it is full, it is full.
We can only reduce it's displacement by limiting the opening time or limiting the inlet pressure or both.
