Switching Gas for different tune?

Switching Gas for different tune?
This may be a sillly question but I still have to ask. I'm using the street tune on my SCT3 tuner that I bought from AM with Bama tunes. If I wanted to try the performance tune, which uses higher octane fuel, how low do I need to go in the fuel tank before I put the higher octane in it? Woult 1/4 or 1/8 of a tank be good enough or should I try to completely drain the tank (which is obviously more difficult to time a gas station stop)?
What have other done?

Even though your PCM doesn't have the range of adjustability like some other cars, it should be able to make enough adjustment for minor octane differences to prevent detonation. Of course, if you are going to run a 91 octane tune for example, you can top of a 1/4 tank of 87 octane with 93 octane.

I'm going to run it down very soon and try the next up tune. Still having a few issues just getting the car running good (vaccum leak in the crappy BBK CAI apparently, which I still am working). Thanks to all!
