I receintly had the borla stingers installed along with a vararam intake with a dyno tune. Since the mods I have noticed a sound that sounds similar to a blow off valve when I tac the RPM's up. Has anyone else noticed this??

Agreed.

There's a well known intake "whistle" sound that many have experienced. I think there might be a TSB, but I don't remember.

I had this sound, but the big centrifugal "muffler" I put on the intake manifold made it quiet right down.

Personally I like the whistle of the intake. After a few thousand miles it will quiet down by itself.
I agree... I kinda like it as well. I get a similar whistle (more like a hissing sound) on my 2004 rubicon that has a snorkle intake.
