If the wastegate of the turbo opens, it really is a question of turbo versus non-turbo. With the wastegate open, reducing the intake restriction will only mean that the wastegate opens further.
Hmm. Good point. I hadn't thought about that. And at highway speeds, these cars run with the wastegate open almost all the time, don't they?
I suppose I could argue that the more the wastegate opens, the lower the exhaust back pressure will be and the more efficiently the engine will "breathe," but that's got to be a pretty minor effect.
