heres the deal....when your blow off valve is atmospheric it runs super rich because it is adding fuel for the air that is supposed to be there but has been blown off. That coupled with the fact that when you hit your brakes you are drawing power from the alternator which in turn makes your crank work harder. Those two events coupled together allow the rpms to drop dramatically if not die. If you are that worried about it recirculate your blow off valve. Tightening it all the way won't do anything for you.. you will have to run a tube from the b.o.v. to your intake after your MAF sensor.
