Anyone who uses ITT to set cruise has a lack of system understanding. Imagine if you have a plane with a 10% torgue dif when matching ITT, does it seem logical to fly with a 10% torgue split? Better get ready for some trim to keep the plane from flying sideways.
There are times as mentioned where torgue is limited due to temp, so you need to bring both engines back down to allowable torgue while maintaining ITT limitations, you still do not need to match ITT
We have a FO in IAH who matches ITT and is looked at like a buffoon
