Hopefully Greg will let us know where we screwed the pooch but in your example, there is still no allowance to modify the physical characteristics of the OEM MAF. It was our intent to make sure the car breathed through the factory AFM, MAF, etc. no matter what you wanted to 'add' that could talk with your ECU.
