I've been rollin around with my apex-i b.o.v and I love the hard whoosh sound it makes. But today it was unexpectedly like 70 degrees in FL?? and it sounded like *** cause it did that flutter noise thing every time I blew off.

Anyone know what causes this? I was runnin hard on it too because i thought maybe it was because I was at low boost but it wasn't that either.
