No expert but it sounds like classic BPC symptoms. Does it happen only if you're pretty aggressive, or will it overboost even if you very lightly increase pressure on the gas? In my car with a bad BPC it wouldn't overboost if I was really gentle.
If it was the hooter I believe you'd get underboost, the diaphragm wouldn't hold the pressure.
If your car is modified you'll likely need a new hooter soon, especially with overboost occurring. I highly recommend the Forge metal one from genuine saab. GL with your boost issue...
