Which tune for ‘22 3.5?

I’ve read a good amount about the performance tunes from 5 star, and am curious if anyone with the latest Gen f150 has any feedback they can provide? Is the difference between stock, 87 and 91 octane tune noticeable? Also how did you tune these now? I heard you have to access the computer under the hood?
I don’t tow. Just looking at a little more performance
