Bad turbo?

What would be the signs of a failing turbo? Mine has gotten louder[maybe just the new tune?]. My boost is also falling off roughly 5 psi. When I hammer it boost goes to 34 then falls off to 29ish. I don't have the LBZ mouthpiece on yet but i ordered it a week ago so it is on its way.[fingers crossed] Is the stock LLY mp a big part of my problem? I have another stock charger i can put on if mine is toast but I really don't want to unless i have to.

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.

I also had FASS lift pump put in at the same time. Could that be the loud whining sound i am hearing?
