[Fight Club] When Tyler is present, who is in control of the body?

First, I know I'm breaking the first two rules for posting this.

Kind of a simple question, when Tyler Durden is around who is actually "in control" of the Narrator's body? Does it change depending on context? When the Narrator is having a conversation with Tyler do they switch control depending on who's talking or is it more like just one is a voice in the other's head?

Whenever there is an action taken that is observable by others *and* has physical effects, it's the person doing that action that is in charge.

For example: 
Jumping on Lou, Tyler.
Destroying something beautiful, Narrator.
