why is my intake whistling at me?

my bbk just would jam open with the blower and make the car rev like crazy, so i ditched it for an accufab and never touched it since.

WOOOOOOOOOOO WOOOOOOOOOOOOOOO WOOOOOOOOOOOOOOO
 
My accufab 65mm on my cobra intake whistles a little bit when i give the gas.
but only in the morning, you should be up fixin breakfas anyway. woo woooooooooo
