1. leak in the connection where you tapped the hose in or at the gauge end.
2. loose wastegate actuator
3. cracked wastegate
do you feel your car jerking around when you boost? 10-15 is a pretty big range

Since you said the boost needle flutters and not boost. It's a needle dampening problem not a boost issue as stated above.

If it came with a t that has a built in pill you should be good. Some come with an in line pill inside a rod that you enter into the tubing too. Take a pic of your install @ the bpv so I can see it.

Dont touch the actuator right now. You arent surging. Its pretensioned so you dont want to **** it up if you dont need to. Even when i was surging i didnt touch it i just replaced the restrictor pill a little bigger.
