Hi people. I want to try my GTR without the dump valves. It's got the standard recirc pipes on. Is there something I can adjust in the bov to stop them opening for the minute to save removing everything. Or could I pull the vac hoses off and that would stop them working? I just want an easy way if poss with going to the hassle of pull stuff apart. Oh and I'm running steel turbos and iv done my research on what happens.
