"This is a FrankenCIS question. I'm told the air temp should be measured closest to the point of metering, which would either be right before or right after the metering plate. So either in the air filter or in the elbow to the BOV or turbo once that BOV is gone."
Well that's wrong if air temperature readings are important to you or your fuel injection system because with both air temp locations you listed in your post you're measuring air temperature before it's compressed by a hot turbocharger and before the intercooler if there is one.
Cold start, steady cruise, and idle wouldn't matter but if correct air temperature readings while boosting matters for AFR calibrations it's the wrong location.
