The EMS doesn't override the power gains, it maintains the same air/fuel ratio regardless of how much oxygen you have coming into the engine. This is how all modern fuel injected engines have worked for the past 20 years. Anything with an oxygen sensor will adjust fuel injection based on the amount of oxygen in the exhaust gas. If you add oxygen, no matter where it comes from (cai, turbo, nitrous), its going to inject more fuel.
