Plugged both vacuum lines and can't say I notice much difference.

One question, not sure if I'm talking boll*cks, but since the ball sockets + linkage that is attached to the first flap inside the air duct next to the air filter/egr is also connected to the accelerator cable/throttle linkage, does this mean that the engine could be starved of air when you put your foot down as the flap closes but the egr doesn't doesn't open with it?
