I understand what boost is. But how do people decide between compression ratio vs boost level?
And is 9.47:1 too much for a boost engine?

I'm not talking about buying a whole system like J&S to control my timing. I'm talking about creating something showing me direct output of a knock sensor. That way I can adjust my own timing accordingly.
Why spend $500 on something that will always pull my timing back to the same place when I can just save $450 and have something tell me where to pull it back to myself.
