Ignoring things like units... power is work/time, work is force times distance.
So, power = (force * distance ) / time
distance/time is velocity which is proportional to rpm (assuming no gear
force is proportional to torque (depends on gearing)
So, out of this mess, we get:
power is proportional to torque * rpm
BTW: the G-Tech calculates hp from m*v*a. It measures a (acceleration)
from its sensor, you enter m (mass of car) and it calculates v (velocity)
by integrating a over time.
