wastegate sluggish code

123511 wastegate sluggish on mhd

I was driving up high in the mountains, not particularly any hard driving and I hit the gas got a dtm and this code. When the car gets above 1700ish rpm I just get a loud whirring noise. I haven't pushed it past that yet but the car idles fine and oil/coolant temp, oil pressure, afr all seems to be okay. The code doesn't go away with clearing.

Any thoughts on what to look into?
