DSM's boost hits pretty hard. In newer cars the wastegate is designed differently so you don't notice it as much, but the sooner it hits the better, sounds like you have a turbo that's in good shape.
if you don't like the way it is, you can turn the boost down and it won't hit so hard when it comes on, but the tradeoff is you'll have less power.
