Compression means little when you can control the boost. Meaning if you cut a point off the compression it is not going to run much different because you can control the timing and boost. If you have too much compression you will hit a wall where you just cant run any more boost no matter how much timing you retard. It is a bad idea to retard timing anyway because it makes the cylinder less efficient and increases heat on the head of the exhaust valve.
