You've obviously never driven with my Grandma...
If you use 93 octane with your 87 tow tune, you do not have to make any adjustments to the program, but...
You might want to increase your timing to account for the higher octane. As the Dr. states,

The best I can suggest is to try adjusting timing a little bit to see if it perks things up. Add ½ to 1 degree at a time and see if there's any improvement. If there's nothing by 2 degrees, then put it back to stock. Sometimes, even backing timing down a little seems to help. Each vehicle is different and, like fuel variances, there are many factors that can affect performance.
