I just put ADD w1 BOVs on my 2023 Stinger GT2 AWD. After a couple days I stopped hearing them. In the beginning they were loud and made your typical BOV pshh. I replaced the vacuum lines, still no sound. I replaced the vacuum lines with thicker walled tubing thinking they were collapsing. I still don’t hear them under load. If I rev in idle and let go of the gas I can hear them purging, and when I put my foot back on the gas I can hear them stop purging, but only at idle and never under load. I’m thinking of putting the stock recirculating valves back on and leaving them in a vent to atmosphere configuration. Could it be the BOVs or is it my boost solenoid? Under load I’m still makin boost on the boost gauge and I can hear the turbos spool as normal. I’ve also tried adjusting the tension screw, and I’ve lubed the BOVs. Help is appreciated.
