I could be wrong, but doesn't our mafs sensors have the IAT resister on the back side of the maf with the MAF signal sensor in the front? I think overall it should still receive the same temps inside the pipe no matter what. The stillen water to air setup still reads consistant iat temps with them backwards. We all know those IAT temps are not even close to what they read by the time that air hits the motor.
With that being said, it couldn't hurt to put them the right way if they are mounted wrong.
