Default Changing DSinTune 87 to 91 canned tune.

I have been running the 87 octane tune with 89 in the tank since I bought my tuner. Recently, my small town decided not to carry 89 octane and I all but refuse to run 87 octane. This leaves me with one option, 91 octane.

So my question is...after I've run a tank of 91 through and I'm ready to retune for the 91, should I return to stock before I do the retune? Or just go ahead and jump right up to it? Also, will I need to reset my changed parameters, ex: throttle, revs, speed, trans?

Thank you in advance for your input.
