I know that it's calibrated. I've said that multiple times throughout this thread.

If you know that calibration you can apply a scaling factor. That is how the MAFia or Mafextender works.

The MAF will follow the same curve throughout its entire range. Just because Ford only uses the first 5 volts, doesn't mean that you can't use the next volt or two to expand the range. Yes, there is a limit. It appears to be in the 7 to 7.5volt range.

Using an op-amp with a perfectly flat response is a great way to do it.

If you don't believe me that this works, and works well, talk to 1turbofocus aka TurboTom on the FocusFanatics forum.
