Before the inlet port? What do you mean? Most tee into the MAP sensor line or delete the AIH and use a tapped plug for the fitting. Like this:

Mine is teed into the MAP line also.

The area you circled is PRE-IC. You should move it to AIH or MAP sensor line.

Edit: Actually shouldn't make much difference but you could get a leak in one of the four connections before the boost gets back to the cold side of spider and not have an accurate reading, or know you have a boost leak.
