Initial PIDs config in mission planner

I changed the prop size on a quad that I have from 18in to 15in. When I go to the my mission planner initial tune section and I enter my data it won’t give me new PIDs. Am I doing something wrong?
6s battery
15in prop

Probably.

Even better than that, are these instructions on what to re-configure when you change the props

.

I use that initially to configure it but changed the props. I assume I need to download the latest version. Will do thanks
