    What kind of IATs are you seeing? Or wouldn't you want to monitor closer to or in intake IAT?

    You have to guesstimate how much heat is transferred to incoming air...

    if intake is getting hot, sure move the balance toward ECT... when you have it right, things like VE and trims fall into place.
