IMO, you'll probably want to switch to a 91 octane map pretty soon. You're basically making your current map lean out the car a little because it expects 93 octane but you're only giving it 91 (which, I hear, isn't great quality in some parts of California, Nevada and Arizona). It'd be pretty safe going the other way (ie. 93 octane with a 91 octane map) because rich is better than lean, but probably not the best idea vise-versa.
