Default loud sucking on idle

My 99 7.3 has a problem when it kicks into its high idle mode when it's been started in cold weather. It idles smooth but once the high idle comes on to warm up the truck a very loud sucking noise can be heard coming from the exhaust. However the second you touch the accel pedal and the high idle mode kicks off so does the noise.

Any ideas?

I think its the EBV Valve on the turbo pedestal that causes that noise when it closes to help warm it up faster. My buddies used to do that till we got ride of the factory pedestal. But I could be wrong
