Hack thought for MAS system???

By adding air after the MAS (is that a speed density system or a mass
system?) I would assume you would use the same diameter/flow intake as the
MAF, thus you might effectively halve the reading the reading the MAS
sends....running lean. It might be far easier just to increase the size of
the sensor by using a Hitachi type MAF (if your car is mass based) from a
Mustang, Mustang Cobra, Thunderbird, etc. That should flow enough air for
over 300hp, then just have someone or yourself redo the tables to take in
account for a lower voltage reading.

Your going to run into problems by "leaking" air into the system after the
sensor knows about it, maybe you can cut off the extra air flow by putting
some sort of door on it...like a secondary throttle body. Hondas have
problems with idle and low speed driveability when they have extra air that
the speed density ecu doesnt know about.
