Question: Do I need to empty my gastank?

Hey guys,

I recently got a tune on a flasher that is gonna put my car up to 91 octane. The programming as it is right now is stock so I'm using regular. My tank is half-full. Do I need to empty it and put in 91 before I tune, or can I tuen it andrun on the 87octane for a few days?
