unplugging the maf puts the car into speed density mode. it still runs ok. the problem is, the tables it uses for fuel calculation without a maf are a bit on the rich side. but you can have them tuned so they're accurate and ditch the maf
maf systems are more forgiving than speed density (and dont require as much tuning for bolt-on mods), so i'd keep the maf if possible
aftermarket mafs aren't worth it. the stock maf flows enough for 400+hp. the ecm has a maf calibration table in it, and aftermarket mafs dont match it. messes with your tune.
on ebay I see larger maf bodies that house stock maf's. That said, mess with the maf leads to a long path of misery.
First it will stop working, and you are going to go, shit!!!!
then you are going to order one off of eBay thinking it will work since it's 1/2 the price, either a used one, or a new Chinese POS, and then when that does not work and you just tossed some money away you will:
buy a used one off of this site, junkyard, or new and that will be your 600 dollar lesson that you should not mess with the MAF on a street driven car.
