I'm using BP 93 octane and this is my first time doing a log.
I have knock around 5,000 rpm 1.5 degrees and around 6,000 2.5 degrees. Should I switch to the 91 tune with the 93 fuel I'm using?

Id start by adding a little fuel in the upper rpm range and see if that clears it up.

And I can do this from this tuner?
How would I modify it? I'm new to this
