LS4 Throttle body

I'm tuning a guy with the LS4 throttle body, what do I have to put the area scaler thing at in the Idle airflow table?

I just changed mine till it idled and revved smooth in the driveway. Took all of 5 mins. Runs fine now but first is a little rough sometimes but the is just the nature of such a large tb.
