we used t do this in the mg/rover scene.
the MAF's even OEM bosch ones where naff. They would get ruined very quickly with oiled panel filters (k&n etc) and left you with probems regarding boost not going very high due to low fuelling. We used to bridge two connectors in the plug with a paper clip as a temporary solution if the car wasnt mapped yet, essentially feeding 5v to te 0-5v sensor, and it fuelling max for that set revs etc. The cars when mapped were very much so MAFless maps, due to the problems with the maf.
It made for the car being a bit smokier at times and mpg MAY have suffered, but we still returned 50+ on them when drove right. basically it made the whole cars driveability depend on your drivers wish etc instead of the maf
