I also wouldn’t breathe too much into the BOV venting. Hyundai’s boost control systems are weird and the BOV goes off on my car at all sorts of random times. It’ll even double vent sometimes. I know people had problems with the BOVs on the VTs and the only one that would activate as fast as the factory sensors needed was the Synapse models. I’m pretty sure Cyngus is a big fan of them for this reason.
