So when ever I let off the boost (not while boosting) I get a bov fluttering. (could be called compression surge whatever I dont care). I read up and many say that its not damaging if its only happening when you let off the throttle but its a big problem if it happens under boost. Anyways, I have a 1g bov and the fluttering started happening after I did a 3in gm maf install on my upper ic piping. At first I thought it was because I moved the whole ic piping forward a little bit causing a kink in my vacuum line but when I replaced it with a long line the issue still occurs. What do you guys think the problem is and how do I fix it?
