Actually, a little knock does not neccessarily reduce power. In the very
early '80s, I was working on a co-operative project with the european
branch of a major US car manufacturer on knock control.
Their engine specialists remarked that the reason they wanted to eliminate
knock was because of owner complaints. I was told that a little low speed
knock did not damage their engines and in fact they produced MORE power
under light knock conditions.
So going for a LOWER octane might improve power!
