I'd try the Forced induction or JDM tuning forums with your question; I have no clue, sorry

 

Bobby...do you have a wide band and do you have experience tuning with the VAFC? Not trying to be a jerk and you may have tons of experience...I don't know...but if not...get the settings to 0% correction and leave the tuning to someone who has the equipment and experience. If you lean it too much accidently, you'll burn a valve.
