coolant problem

Looked under my hood today and the degas (Coolant) bottle is squirting coolant from the lid all over the place. Does anyone know what is going on here? Also driving down the highway or a quick takeoff, when I give it some throttle the turbo/air intake has a high pitched sucking sound like a throttle body spacer on a gaser. What the hell. Also some days going down the highway at 115/120 kms, the turbo boost guage is almost at 1, other days it is at 1.5/2. Does the cold temp have something to do with it?
I'm driving an 07 6.0 F-350 HD. Anyone out there having the same problems?

Thanks,
Mike

Is your coolant level at the min line on the resevoir? If not I'd remove coolant till it's sitting at the min mark. If it keeps blowing coolant, the next thing I'd try is replacing the cap. They have been known to go bad. If that doesn't work, then I'd start thinking about EGR cooler issues or HG issues.
