One thing I forgot to mention;
Higher comp pressure doesn't neccesarily = more power,
it does however help pumping efficiency in natural asperated motors but, that is not an issue with blown motors.
Running high comp with boost requires a fuel with a very high motor octane. Some will argue this next part, many high octane fuels do burn slower, however there are some that offer a good burn speed and good octane #'s.
While the theory that you can make more cylinder pressure for more power...
