What would happen if you drive with the Maf unplugged?

Not much but you may get a cel and car may not be as responsive if originally there was no problem with the maf sensor.

If off then the ecu just depends on the MAP sensor info for making its calculations.

You tried borrowing a known "good" maf?

Well when I had my remap they said they were getting very strange Maf readings, tried with another mafand was the same! Gonna try a new map sensor?

Said they achieved around 20 extra bhp when the Maf was unplugged
