P0234

Hey all!
So I've owned my 2015 since new. Finally put the GH tune to it. (Don't know why I waited) I'm about 1000 miles into it and I'm getting a stutter on acceleration and P0234 code. Do I need to change my BOVs?

Check the following, get a log to the tuner:

• The turbocharger/supercharger wastegate is damaged or sticking
• The wastegate control valve solenoid is sticking
• The wastegate control hose is getting blocked and the boost pressure cannot be relieved quickly enough

Update: I found bad vacuum line. Replaced it and it's all good

Any chance you mind sharing which vacuum was causing your Pcode?
