Error in yaw rate while using the 3DOF dual track model in SImulink

Hello,
I am current using the 3 DOF Dual track model in simulink from the vehicle dynamics toolbox. In there, i am using the option of external longitudinal forces to replicate the torque generated by the motors on wheel. When i do that, even though i applying the correct torques while steering the yaw rate being generated is very less, which would not be the case in a real life scenarios.
Can someone help me what to do, I want to basically create a yaw rate controller for cornering stability by manipulating the on wheel torque, before I apply this logic in real life i want to test it in Simulink, but somehow this is not working properly and the yaw rates that comes as an output from the block is inaccurate.
Thank you,
Rahul

Rahul, could you clarify your comments above? You said you're "applying the correct torques while steering". Which specific signals in the block are you using and how are you determining the correct values for them? The yaw rate calculation is shown in the Vehicle Body 3DOF help page:
