LSA install question

Really getting to the last step on my LSA supercharger install. Got the starter tune installed over the weekend and the only thing that popped up was it sounds like I have a leak on the pcv line that runs from the front of the supercharger to the rear of the driver side valve cover. I thought at first it was the fitting that connects to the valve cover, so I swapped it out with a different one, no change. If I pinch the line the noise stops so it is that line. Right now I've installed a heavy duty rubber 3/8 line with hose clamps at both ends to eliminate the fittings and still no change.

Is it just moving enough air that I hear the air whistling through the line?

Thanks.

Use fuel injector hose to remove the hissing noise. I had to do that as the noise sounded like a vacuum leak...

FI hose is Teflon lined...

Might be a good time to consider a Catch can? They do move alot of air, and blown is worse.

Take Dons recommendation though, along with confirming the hose does not have a hole or cut somewhere. I've bought brand new line that was cut somehow before.

Pretty sure there isn't a cut in the line, the sound actually seems to move to wherever the most line is bent the most. I have been considering a catch can, but ADM and my tuner both didn't think it was needed. I may still go with a catch can setup or get the Teflon lined hose, but it doesn't seem like this is anything that would stop me from getting it dyno tuned.

Thanks for the answers.
