The 1986 to 1989 Corvette, Camaro and Firebird use a Bosch MAF sensor that
is a 0 to 5 Vdc sensor not a frequency type sensor (like that used on the
1994 and newer Corvette, Camaro and Firebird).

One thing you can try is using two stock MAF's is parallel with the ECU
only connected to one MAF (but air flowing through both) and then using an
injector twice the size the computer thinks it is. It is VERY important to
design the air intake so that the same air flow goes to both MAF's - test
it on a flow bench with a voltmeter if possible.
