I pass in Ontario, Canada, as we have less of a visual test. (however as of this past spring we don't need to test anymore).

My emissions themselves were clean. Many here report passing even with kittenless deepees, so long as it's not visually observed.

I would think it will improve your odds (there is a scale, not an on/off) of passing if you run in Map 0 for a bit. This will let the DME, 02 sensors, etc, adapt to fuel and boost so your burn is optimal.

My BMS DCI have way more surface area then my previous intake (Ultimate Racing Cold Air Intake).
Further, it's nice to know they are well certified.

** EDIT ** I have not tried to pass since the BOVs. I suspect the noise will make them look closer. Lucky me, our smog-tests are behind us now.
