My dyno experience data points are all from Dyno Dynamics units and generaly stock engines/drivelines fall into the baseline standards (varriation +/- 5%):

2.0L WRX 02 to 05 = 160whp
2.5L WRX 06 to 08 = 185whp
2.5L STi 04 to 07 = 225whp

(Mustang dynos tend to read +15whp more than dyno dynamics)

Thus if Mcganz's WRX put down ~225 as a baseline (which means the dyno is waaay off), yes he could have pulled 325whp which means his mods gained ~100whp. But not 150whp w/o some combination cams/race gas/water-meth. Those turbos/heads just dont move that much air.
