MAFS/ airflow problem- weird noise - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I had just gotten a new blow off valve and aluminum custom piping made for a t28 install. I have a Greddy Type-S blow off valve (which I rarely hear anymore) and a SARD intake. It was working fine, but then I went to Japan for a year, came back and now I never hear the blow off valve. Instead of hearing the blow off valve, I hear a turkey-like sound (sorry, no other way to describe it) coming from the air filter/MAFS area. My blow off valve is on the other side. I took off the airfilter and cleaned it up, but same problem. Has anyone had a problem similar to this, or have any idea what it is and how to fix it? Thanks.
