question about a/f and timing

2007 jeep srt8

I am having:
st knock of 5 on a 93 tune
st knock of 2 on a 91 tune

looks like adding fuel is fixing the problem. My question is that by adding more fuel in the 93 tune versus less fuel in the 91 tune to fix the knock issue, which one will produce more HP?

may be a stupid question..sorry

The one that knocks the least will make the best power.

Only real difference between the 91 and 93 tunes are the amount of commanded timing at WOT.
