Yeah I read it. There's a lot I don't agree with in their explanations. I understand how a turbo works, and this just makes the turbo easier to bolt on. Mounting a turbo further back, or making a turbo run cooler, or basically the majority of the things they talk about, will not add power, it will actually decrease it. If you understand how a turbo works, then you know that it uses the heat from your exhaust to spin an impeller on the intake. If you reduce the amount of heat, you reduce the speed of the impeller. Denser air will make the turbo run more efficiently, that is true, but not if it has cooled significantly. You take the same turbo and mount it closer to the engine, and it will make more power, and spool faster.
