Do I need to run vacuum tubing for afr or boost pressure?

I'm working towards pure stage 2 and eurocharged is saying I need a bunch and o2 sensor for a wideband for tuning. I want to go with a p3 guage but their website says you only need the obd2. 2011 e90 335i xDrive

I am so confused, what is the question? Only reason to replace the O2 sensor is if it is bad. The stock one is wideband. If the P3 gauge uses OBD port then you don't need a vacuum line to it.
