I am doing a 13BT swap and removed the emissions. I was wondering if I'll need to "tap" into the ACV plate and use the S4 N/A pressure sensor or buy a S4 TII pressure sensor... ?

 

you would use the t2 pressure sensor

 

Use the turbo pressure sensor and use the nipple on the UIM.

 

Yes, and it has to be a Turbo one.

You have to use the Turbo MAP sensor but you don't necessarily have to tap is into the ACV block-of plate. It's the most correct of several correct options. Teeing into the BOV line is easiest and works okay.

You realize half of nipples on the UIM aren't suitable for the MAP sensor? Telling him you use "the nipple" isn't much help...
