With a tune it can change how the turbo sounds, and if you're making 29psi then it's 100% healthy. It's normal for it to spike just a little. Once you do the mouthpiece upgrade you'll notice a nice difference as well.
Don't waste your time changing chargers, the other one will just do the exact same thing... make noise and boost :tease It's perfectly fine, don't sweat it.
