Underbalanced Torque and Drag

Folks of the community.

When designing and engineering wells for underbalnced drilling, what are the changes that need to be made to the Torque and Drag models to make them more realistic? (I think most torque and drag software is designed with overbalance and mud in mind).
Surely the lack of dampening and different bouyancy effects must be taken into account somehow..???
