Terry, I generally wait a month after DC installation to tune the piano, but longer can't really hurt anything if that seems right to you, except that more time will pass before the piano is tuned. Since I have heard of instances where humidity changes cause the piano to change pitch while being tuned (that's *fast*!), my hunch is it doesn't take as long to reach full effectiveness as I formerly believed.
