So I got a turboxs sml hybrid bov for my 2014 genesis coupe 2.0t. I installed it right when I got it and when I tap the gas in neutral I hear a fluttering sound from the turboxs blow off valve I just purchased. I’ve seen videos on the internet on the blow off valve on other peoples genesis and they all have a nice whoosh sound to it, but when I installed mine it has a pretty loud fluttering sound whenever I let off the gas. Any ideas on what can cause this fluttering sound??? And how I can fix it?
