You can use the motor calculator to find out what Inanek mentioned, but instead of using thier preset motor controller options, select a custom contoller instead. Then set the controllers phase amps (90 for phaserunner, 70 or baserunner), and heres the key part, set the battery amps to whatever your batteries rated BMS is (mine is 50 amps but yours could be lower, maybe 40).
Use that to compare the torque value when the motor is at about 0kph (it will be its maximum torque)
You might see some increase in torque but from personal experience the new V6 phaserunner is really buggy and having issues with overcurrent faults. Lots of jerking at motor start and even faulting out, so much time spend adjusting the current regulator Kp value.
I suspect part of the problem is the autotute not correctly identifying the hall sensor offsets, but I have not tried to tweak that.
