Help with an issue

So I'm having the following issue:

On half acceleration the car bucks pretty bad, with the boost gauge going back and forth between 5psi and 0

On full acceleration it boosts normally and with no throttle it has full vacuum. On half throttle it twitches between ~10inhg and 0.

I'm getting the following codes:

Do I just have a massive boost leak somewhere? I checked the intercooler hoses and the hose between the charge pipe and the throttle body and everything seems tight.

Ready to race!
Mine use to do that. I had a boost leak. Never pulled codes kn it tho so can't compare yours to it sorry. Mine does it a lil around 2 500 to 3000 rpms on part throttle.
