Fluttering noise under load/boost

Whenever i accelerate my car makes a fluttering. Almost ticking noise when under boost. Or under load. I have a video with the sound. I did just order a new coupler for the supercharger. But this seems like a separate issue. Here's the vid: ignore the loud supercharger and exhaust. If you listen carefully you can hear it in the background. Help me http://youtu.be/AdyRrcOqc6s

if that was a turbo id say it was compressure surge, when turbo is pushing more air than the car can injest, so it goes back into the compressor blades, which is bad. with a supercharger I couldn't tell ya, do they do the same thing

We figured it out... One of the bolts on the down pipe where it connects to the header was completely gone. So it was just an exhaust leak. We were really surprised that it caused that much of a noise.
