What is the difference between the two? It seems the timing chart pulls from the dynamic cyl air but there is a user defined PID that comes with HP Tuners. Just wondering what the differences between the two are.

calculated cylair is calculated from the MAF airflow and RPM. cylinder airmass is directly logged from the PCM.

So these two should be in line with each other if your airflow is setup correctly? I would expect discrepancies between them in rapid change states of the engine though.
They shouldn't be like drastic differences though in steady states (i.e. calculated cylair .67/cylinder airmass .85) right?

in theory yes at steady state they should be close.

since the calculated one is MAF based, if your SD-related tables are miscalibrated, and every time your hybrid mode will be using the SD portion, or just run in pure SD, the calc one will be off. Also, if you've gone pure SD, modded things, and have not touched MAF since then, the calc one will be off as well.
simple version: use the dynamic one, unless you really know what you're doing.
I always use dynamic because that's what the PCM is actually using as spark lookup.
