SLOWBOOST;3369947]yeah, maybe i shouldve explained this better. since it only works when the wastegate is open, and having it set to open when there is boost will work. youd be able to turn the screw to close it if you dont want it open, and open the valve to open the dump. with a cap down there, youd probably be opening it while your driving around seeing exh temps of 1300+. i dont really like putting my hands down there when i dont have to. i dont see why you cant just get a open o2, dont boost if you dont want to hear it, and when you do want it boost it.
