Default Air and map sensor vacuum lines

When I bought my car it had the AIR tubes and EGR off already. I don't think all of the lines were removed properly. There is a vacuum line going to the map sensor on the back of the intake that comes out of the factory wire loom. I assume this needs to be left on the car?

I added a picture for clarification. The two blue lines are for the AIR and can be deleted, correct?

The red line is going to the map sensor and this vacuum line needs to stay connected, correct? I will plan on capping part of the "T" fitting with a vacuum cap (the part that leads to the AIR assembly). In other words, I can not cap off the vacuum cap going to the map sensor, correct?

The port that you have "save" beside goes to the HVAC, so if you want the blend door to work it needs to be hooked up. The other one that you have "remove" on can be taken off and yes you can cap it when you remove it

Yeah, I want to save my A/C, etc. Can a boost guage be placed off of the "T" instead of capping it off (I do have a procharger)?
