Loud high pitched noises in boost are usually caused by boost leaks.
Are you still getting full boost? Might want to stay off boost until you get it figured out...if you have a big leak you might be working your turbo too hard to achieve full boost, which is bad for the turbo.
The GM BCS just controls boost in a different way than the factory BCS so it shouldn't make any weird high pitched noises. Mine just clicks like mad.
