Update: Went to do this. Got the top nut off of the wastegate arm with ease. I wanted to check and make sure I could access the vacuum line to the actuator before I took of the lower nut which held the wastegate's position. I could not get the vacuum line off of the actuator. Likely due to the fact that, I have large hands and there is not much access to that hose. I could get a little grip on the line but she was really on there and it was not a regular vacuum hose, it was so sort of braided line. I will be trying this again but I am currently seeking some advice.

Is it safe to use pliers to remove the vacuum hose?
How would one get the bottom nut on the wastegate arm loosened?
What size hose fits the wastegate actuator fitting?
The wastegate should be completely closed at the BMW recommended pressure of 5.9 In.Hg, is this correct?

Thank you in advance!
