My recent CA SMOG check experiences have been with techs that took their job surprisingly seriously, especially on the van. I had one check all my evap lines, and after nearly 30 minutes, comment that while they weren't in the stock location, I had in fact manage to connect them all correctly.
I'd fully put an EGR delete back before going to an unknown CA SMOG test. That seems like the sort of thing they would explicitly look for.
