the line is coming from the intake manifold actually, it senses turbo pressure in there.
at a minimum, plug it.
however, since you now have no fuel limiting, it's a good idea to plumb in a boost gauge to at least see what your turbo is doing.

running 9-10.5 psi at WOT. Low/high? Car accelerates nice out of the hole, shifts are buttery smooth but you can feel them. Where did you guys mount your boost gauge?

9-10. is average. your wastegate is working fine.
some adjust to get 12ish. above that is a waste with an unaltered IP
