at what rpm do the air ports open. cause i have them tied down right now. and i redline the car every once in a while. but i bought the 5th and 6th port header so that will open it as soon as i put it on, but i dont have $ right now. but if i leave them open will it do anything if i redline it with them closed. cause i notice a hugh torque loss whenever their open. and i want some of that back.
