Some intake are also more prone to hearing the flutter / dump sound. :happy2:

Old thread but hoping for a response. I've just fitted a forge twintake to my BWA engine GTI K03, it's totally stock apart from the twintake .
I don't get any chatter unless I tap the throttle a few times on boost other than that it is just a woosh! And darth Vader noise under load Is this normal. Was thinking I may have a faulty DV or something. after reading this thread am I correct in thinking this is a good thing that I'm not getting loads of flutter or not .
