Default Typical Cylinder Airmass on healthy HCI Z06

Just wondering what kind of Cylinder Airmass you guys are seeing/hitting on a typical HCI Z06 in the 600whp range...

Had my car retuned after a header swap and my tuner changed up my tune, for the better. I only picked up about 10whp and 2wtq peak but he was saying that the car was hitting down into the 1.26 g/cyl range and that I saw notice a considerable difference on the street, in the upper rpms. Unfortunately, I never paid too much attention to that table before, so I don't know how much that changed.

I try to watch the changes he makes just to learn a little more about the process.

Mod list is:
Lingenfelter ported stock castings
.050" mill
Mamo MSD
NW102
Vararam
TSP 4.2 cam (248/260 .656/.656 111+3LSA)
ID1000s
E85
ARH 1-7/8" headers w/ catted x-pipe
LG GT4 exhaust

Put down 612whp/537wtq, uncorrected. Somewhere North of 630whp/560wtq corrected.

1.26 is pretty good.... Was it staying around 100 kpa or higher?

Unfortunately I didnít pay attention to KPa at the time. Iím running the vararam so Iím assuming it was, at least, 99-100

Looking at my logs I'm also getting 1.26 average, peaking 1.30 at some rpm points.
