This is what is stated on the website for PG27 with 9015:

The description implies otherwise.
I'm not really sure if the Dyno testing results are correct( or maybe they are the 775-125 results), surely if the 9015 has a stall torque of 0.36 N.m( from motors.vex) with a 27:1 reduction the stall torque should be around 9.72 N.m( less due to frictional losses) rather 4.8N.m(using online calc from 3.55 ft-lbf)
If the stall torque measurement was correct it points to the gearbox having an output power of 65watts, which doesn't seem correct considering that from the VEX testing the 9015 is capable of 134watts.
