HISSING NOISE EVER SINCE WEATHER GOT COLDER

It was 25 degrees out today and for a while my truck would make a hissing noise (cshhhhhhhhhhhh) whenever i barely pressed on the peadal. it did not make the noise at idle or when i had it press 1/4 the way down or more.
what is this? is this the ebpv? it went on for at least 5-7 mins of driving

Must be your first winter with your truck. We really need to make this a sticky!! The EBPV will open when the truck is under a load that is why you hear it more at idle.

EBPV.....

It scared the crap out of me first time I heard it. My first powerstroke was a van. You should hear how loud the hissing is when the turbo is about ten inches from your right leg!!!!!! I thought I blew an intake boot or something. I still have that van.....just rolled over 321,000 with seven stock injectors and only one trans rebuild.
