What do you guess the evaporator surface temperature is in the current system I have installed? I hope you answered (to yourself) that you have no idea because I'm almost certain you don't. All I know (and all I stated) is that the system works as is.
Why would we now start discussing an issue that may or may not be an issue? To say that something won't help without something else (about which we know nothing) is about as valid as me saying the AC system won't work with elephants living in the blower box - it may be true but who cares?

My mistoke...
Should have said...
More CFM will be useless if the temperature(***) of the evaporator vane/fin surfaces rises in accordance with the increased airflow rate/volume.
More simply said, at the previous lower speed you had already reached the maximum cooling capacity of the system.
"Target" is 33-35F, low enough to provide maximum cooling absent freezing up.
