I was able to get some 24 # injectors and a 80 MM maf sensor (F5oF-12B579-AA AFH80-01A) from a MARK VIII I believe. I was wondering if the sensor is a direct change or what I need to do to make it work.

if i remember correctly i believe the calibration is in the ecu on fords. an that the aftermarket just reclibrates the meters to use with the factory programming. so i dont know if you will be able to make that work or not without some sort of tuning done to your ecu

Another question after doing some research on the MAF.

If I were to use the original MAF sensor and go from 55 MM to 80 MM housing and go from 19 to 24 injectors would the bigger size injectors correct for the extra air coming in.

No. It's would be no different than using the sensor that came with the 80mm unit to begin with. The calibrations will be off no matter what you do.

Let me add... You can fix this 2 ways.

You can get a "calibrated" housing for your original meter. Granatelli, MAC and others make the housing with the correct sample tube for your 24 pound injectors or...

You can get a chip burned for your ECU that will give the correct calibrations to correct for the 24 pound injectors and 80mm meter.
