Forge do a \'twin bov\' kit, but if you have stock twins it\'s generally thought that you don\'t need another bov

Unless you\'re experiencing the dreaded second turbo boost problem

Only one of the denso units is a dump valve / BOV, this is the one closest to the air box, the second one is something to do with the prespool on the second turbo, this is a vent which releases the pressure generated by the second turbo before the butterfly opens at 4500rpm allowing the boost from both turbos in to the plenum!!
