Tim, I think you prob had the best answer, but any reasoning?
If you run the exact same psi and everything else being equal, and you lower the compression, you will actually lose power. But its the benefit of being able to crank the boost up that you are after.

Boost is boost all the time. Compression is just compression on the compression stroke. Raising boost is more than just compression, its raising the volumetric efficiency as well. Thats why its worth more power, if thats what you mean
