You're reading Karman Vortex frequency through the S-afc, not at the ECU. Obviously there will be a decrease at the stock MAS, but there will be no TOTAL DECREASE after the change at the MAS AND the change at the S-AFC (which, BTW, you can't read w/ the S-AFC).

A datalogger can pick up the change (because it only reads the values that the ECU is seeing), but there is always a cut-off at 1606hz, and you can't use a datalogger on your '95.
