Default Turbo is acting up

So my turbo seems to be acting up lately. It's building boost and everything alright, but at lower gears and higher Rpms during quicker accelerations it builds it's boost up to about 20 psi, then drops to about 16-17 and makes a noise that sounds a lot like an exhaust break. Then it shifts and builds back up to 20. It usually does this between 20 and 40mph. It doesn't sound like surging, I YouTube'd turbo surge And the sounds is nothing alike. When I have a slower acceleration from about 50-70 mph it builds up to 20 psi and holds fine. I have a video on my iPhone I can post when i get to my laptop. But maybe someone has an idea just from my description. Any help is appreciated.

My wallet doesn't really want to buy a gtp38r, but if I have to I suppose i have to Ba ha!
