Bad turbo actuator? Just making sure

First of all sorry i found a few threads on this that kinda solved my problem but they were slightly diffERENT than my situation. So when i was doing a pull on the freeway on-ramp i heard a pop sound then my CEL (knock light for me) came on. It went away after more driving but i noticed i couldn't build boost anymore.

Does this mean my wastegate is stuck open? i tried moving the little arm on it and it was really tight. I checked the turbo at idle and it still spins, and i can still hear the turbo spool up a little bit but no go from the turbo.

Checked all my couplers too and i did have a small leak coming from my BOV but i adjusted it.

Do a boost leak test. It sounds like you blew a coupler off somewhere.

Your actuator should be very hard to move.

I would bet on a coupler as well. You should check them out and make sure none of them have blown off.

Good call guys turns out a coupler couldnt take the pressure anymore haha problem fixed, now on to the other problems
