Are you worried about the MAF's restriction?  Or measurement ability?
The '3' engine was NA wasn't it?  That MAF probably has limited 
measurement ability.  Never really looked at it's MAF tables.

Always fun.

Not directly.  With MAF table and code mods you could.  Requires a lot
of understanding.

It is a high freq MAF.  With a range about 400 to 10k Hz or so. (From 
memory...)  As I recall, the MAF tables max out at 170 gps.  Most all the
V-6 MAFs had similar peak airflows as I recall, except for the GN.
