So basically anywhere above 4000rpm, and especially at WOT, the Dynamic Airflow channel IS the MAF airflow. That would be the lb/min to use for this HP estimation.

Thanks for the clarification Rob! That said, here are the revised calculation...
peak RWHP was around 6,100rpm... Dynamic Airflow was 5,600 lb/hr or 93.3 lb/min = * 10 as a representation of crankshaft hp would equal 933hp at the fly . At 838rwhp x 1.18 = 988bhp so it looks like a 6% difference so far?
Now... checking at 6,950rpm... Dynamic Airflow was 6,114 lb/hr or 101.9 lb/min = * 10 as a representation of crankshaft hp would equal 1,019bhp...
Am I doing this right?
