Do you know where and what they are? If not, think v-tec. They open up in higher RPMs (forgot what rpm since its been awhile since I messed with NAs).Well alot of people wire them open because its a myth that it makes your car faster. Only time it does anything good is if they are stuck shut, because then you won't get any top end power. So people wire them open so you get the top end, but you'll lose some power down low.
