Here is an example in excel from data I exported out of HP Tuners. FYI, I will hit just over 11 kHz on my MAF for some runs, it flattops right after 6900 rpm.

I noted that the calculated Mass Airflow (red curve) tops out around 10.7 kHz @ 655.4 g/s (86.69 lb/min), looks to be related to the SAE PID max value. This occurs around 6200 rpm for me. Dynamic airflow (yellow curve) appears to keep calculating and does not flatline like the MAF SAE value.

See example below, overall I think I'm not being limited harshly by not having a big gulp, maybe around 6700 you can see a little roll off in the shape of the curve:
