As I said countless times before, CIS only measures air flow trough it's barn door and injects fuel accordingly. What you do with air after that (compress it, heat it, dump it overboard) is nothing it cares about. With other words, changing discharge air temperature ex turbo won't do a squat to your AFR's as air is not added or dumped past CIS barn-door. Only thing that will happend is that your turbo will work harder and won't be able to pack as much air into engine as with cool temps.

With other words, only thing that really affects your AFR's is general air temps and humidity. As long as you didn't do your AFR tuning in -20 degrees, your 12.3 AFR will have more than enough margins to cover typical outside air temp swings expirienced at track.

Thus this whole discussion is quite moot.
Thank you for your time,
