But do they stay closed to matter what until 3200rpms? If anyone can clear this up for me, It'd be greatly appreciated.
Thanks!

After much research I got the NPP as well. I could be wrong, but if you want to override this all you have to do is pull the fuse, so it is always on OR get a Mild to Wild switch installed aftermarket which will do the same thing but give you the option of opening or closing at your discretion. Hope that helps.
