Just got my 250X running! The bypass valve (the one closest to the throttle body) is putting out a lot of air at idle and higher rpm. Havenít run it in the water yet since I need to fix the pump. Is the bypass valve supposed to be open all the time? I though it was just to relieve boost when letting off the throttle quickly. Do I need a new valve? Iím planning to block off the rear BOV
