because the flutter is stuttering of the compressor wheel as air is pushed back against it through the intake,denser the air(colder) the more harmonic effect you get

the dump valve should work unless the cold is affecting the diaphram or spring,the air passing over the compressor wheel will still be louder the colder it gets though
