basicly its more of a prefrence than anything else, most people run this or that bov becuase their intercooler piping might be specifically setup for say the hks or the greddy style, so they use those kinds.
however basicly if you are running 24psi of boost with the dsm and not leaking, then there isnt a reason to upgrade. however if you are leaking then it would be time to upgrade your bov to prevent anymore leaking
