Default Predator question... 87 tune on 87 fuel vs 91 tune (modded) to run on 89 fuel

Ok... On my DSP....
Is there any advantage to one of these over the other:

1.) Running 87 tune on 87 octane
2.) Running 91 tune on 89 octane but modifying the 91 tune to be proper for 89 octane fuel?

If #2 is the best choice, what changes would be necessary to make it happen?

Also, how do I properly log to see if I'm getting knock etc? What #'s are in a good range and what pids do I log?

Thanks guys!!
