See Mikes comment below.
Area of a circle = r2 x 3.14
73mm = 4183.22 mm2
88mm = 6079.04 mm2
6079.04/4183.22 = 1.45
Assumed offset factor due to MAF sensor calibration at stock MAF housing size.

Where is your sensor positioned in the airflow in the new MAF housing vs. the old MAF housing.
Assuming somewhat laminar flow the velocity of the air varies with distance from the wall of the MAF. If the sensor is measuring too close to the wall of the larger diameter housing it could be reading lower than expected based just on scaling of the area of the housing because it is seeing less air than the center of the housing.
