i just did this to my 92 sc
i removed the maf and reworked it (same injection pulse as the cobra)
what i did was remove the center post and restricter plate and
bore out the sample tube to 15/32 i.d.
i also took off the air box silencer.
i have all the tools to do this if you dont , email me if you want me to upgrade yours.

bad idea..trust me....did a before and after on the dyno and the a/f ratio is a lot more rich. The bigger hole tricks the computer that its flowing more air than i really is...so it speeds up the injector pulse to add more fuel but it runs rich under WOT because o2 sensors are not used. At WOT...all the info comes from the MAF and the stock computer program. I anyone really wants one...they can have mine for like 25 bucks.
 
maf upgrade

thanks for the input.
i havent noticed any running rich problems.
i did this upgrade with the air silenceler removed an a k+n air filter installed.
i have to admit the car runs a lot harder since the upgrade.
