"If the CPU does read a calculated load ..."

The CPU doesn't 'read' load, it calculates load (hence being called 'calculated load') based on the max possible airflow at that given RPM against the actual airflow as measured by the HFM. No way to change it, at least not without screwing other stuff up. You could vary the HFM signal (and there are many boxes on the market to do this) and to get your load down you need to make the signal mean there is little to no airflow. But then of course your DME would be injecting fuel based on the totally wrong (very low) airflow and you would be very lean and probably melt a piston.

"it may be stored in a log as an error for later trouble shooting purposes. "

There is no may about it. You do this and your DME is going to store a 'D6' error code for a 'Vehicle Speed Sensor malfunction' in that the engine was under a calculated load for a specific time but not receiving a vehicle speed that corresponds to diagnostic limits.
