In oem form the MAF is calibrated to read as high as 255 gm/sec..
BUT,
with so much as an air filter change you lose that accuracy.
As you modify things the MAF calibration gets worse and worse, and that's why you have to buy different chips. What most of the chip guys do is figure the MAF is close enough or will get folks by enough to be able to drive the car that they don't mess with the MAF tables.
The tables have a correction based on rpm, that allows for extra fuel.
It's not the best setup in the world, but it's good enough for some guys to run really quick with it.
There are some problems Software and Hardware wise in the stock ecm. That's where the Translator, and MAFless ME shine.
Either of these two systems avoid the inherit problems of the stock stuff.
Changing to a Translator and moving the MAF so that it's a blow thru is another option.
M Pitts several years ago documented that with no other changes removing the MAF in his car was like 15 HP but that was in a draw thru setup. You need to go thru the GNTtype archives for the original claim.
