Yes. BAT's are what to look for and to try to control. IAT's affect BAT's but there's not much you can do about that under most conditions. I like Darth's suggestion to ditch the coolant supply to the throttle body. Makes sense. Maybe I ought to consider a more reasonably sized FMIC. My experience with them on smaller displacement engine (2.0 L) longer runs, and bigger turbos (Garrett T-3 and T-4 variants) on other platforms had left me cold on the ideal.
