Let me see if I can recap. It will scale the entire range of the maf down by lets say 40%. So at an idle of .08, the ECU will see .048. At WOT, instead of 5v the ECU will see 3v. Is this correct? So you would need a Diablo or SCT to scale the tranfer function down for better resolution. IIRC the OEM functions usually only go down to .05 which leaves no room for interpolation.
