Do you look for the airflow at your engine's peak rpm, or when you want the turbocharger to kick in?

I believe you go for idle / part throttle / and at wide open throttle, but don't hold me to it. That's the way it was done when I got dyno'ed, but I have a supercharger and you're looking at turbos......big difference as air flow is concerned
