My belief is if a motor is going to sit for more than 1 month, then the motor should be fogged.
A throttle body injected motor is not a true EFI, its just 1 injector in the throttle body, just an upgrade from a carb, so I treat it the same as a carbed motor and fog it, but that's just me.
Really do what makes you feel good about off season storage, if extra work makes you feel better, then do it, if your comfortable with storing motor with oil film from normal operation......
