It isnt calibrated from the factory for 42's unless you ask for it. The MAF has a specific curve and the EEC Has the variables for the injector slopes. They calibrate MAF's to avoid having to change the injector slopes in the EEC which is the right way to do it.
Guys, stop with the bad information. Ford factory MAF's are not calibrated for any injector size. All transfer functions are handled by the computer and it needs to be tuned via a chip or computer flash.

I understand why you think that, but the recalibration is handled by the EEC. If you put this product on anything other than a Lightning, which has the LMAF settings as a default, then yes, it will require the EEC to be recalibrated for it. That is the required calibration.
