Leaking Turbo?

I have owned my 95 F-350 for about 3 months. It has one of the gold super chips plugged into the computer. This morning it was 25 degrees here, the coldest I have started the truck since owning it. I had it plugged up, because it needs new glow plugs.

For the first 5 or so minutes, I heard a whooshing sound, similar to air leaking out of an air compressor, that I determined was coming from the turbo. It was not constant and when it was making the noise, it would lose some power. Once it was good and warmed up, it quit. Is this normal for cold weather? Is the turbo dumping excess pressure due to cold temperature?

Thanks for your help

Most likely it was the Exhaust back pressure device between the turbo and the downpipe that was working to help heat up the motor. Normal.

nope the ebp valve just cuts off the exhaust when it was cold to not let all of the heat out of the engine through the exhuast but i dont think a 95 has a ebp valve because we have 97 work truck and it never does that!!! like my 02
