It sounds like it just changes the head gasket's thinkness on the fly, so that as the turbo boost increases, it can chnge the compression ratio to prevent pre-detonation on normal 93 octane. It gives the car both low end and high end power this. Genius, but it's hard to create a headgasket that chagnes width, as you're moving around a lot of parts.
