FluxEst Output Torque Error

I am seeing some error in my motorTorque given as the output of the FluxEst. I have a dynamometer that is controlling to torque on my motor. When I set the torque to 50Nm, the FluxEst output reads 70Nm. When I set the torque to 140Nm, the torque from the FluxEst is 222Nm. The torque seems off by around ~1.5. Is this due to the 1.5 scale factor in the power? Any other reason why the torque would be off from what the measured torque is?
