Two very different types of GM MAFs, voltage output or frquency.  Rated by
grams per second.  You'd need to match applications for getting one about
the same flow range as what you need.

??.   MAFs measure Mass Air Flow, which automatically means it, compensates
for temp..

You have to figure what you need before you need to find where to get it.

One of the Ford guys had some flow bench numbers at the ford ecu list, no I
don't have a URL.

MAFs don't care about boost just how much air is flowing thru em.  The trick
is getting the fuel calibration right.
Might try reading some more in the archives, about MAFs MAPs etc
