pop off valve noise

When I am standing over the engine and blip the throttle open the pop off valve is making a loud clacking noise - that I can feel in the housing. Should it be doing this. Even with small blips eg +500rpm this happens.
Also, should I be able to get on to boost with the car not under load, at 3000 rpm +
