Obviously this is an LS application, but it may be the same for an Ls too. I would try the stock etc scalar and add some airflow to your minimum airflow table. Is your idle spark at your commanded idle spark? Is it having to add idle spark? I won?t be near a computer until tomorrow so I can?t check. Once you get your min airflow where it needs to be, you can adjust throttle follower torque.
