This is an excellent idea that I hadn't even considered.  Thanks.

I believe the MAF is used even at WOT with the MAP only used as a
cross-reference. (any 94-95 LT1 guys out there?)  For some reason
the number 471gps sticks in my head as the point at which my MAF
hits its max calibration point.  Above this, the PCM does not see
any additional air coming in.  This means I will have to tune the
PCM to have the correct AFR at max air flow even though it only
sees 471 gps.
