the problem ? dictated by the fact that the mass air flow sensor has an operating range, which goes from 1Volt to 4.4 about, you will definitely have the air to reach the value of pi? high, beyond all measure more, the value is the maximum.
if you wanted to go crazy you may montargli the mass air flow sensor on a 16v, that should be scaled differently, of course, resizing the linearization of maf (a bit like you do with the map when you switch from *2.5 bar *3bar)
