Message which are not the same thing.. They have a relationship, but it has a large, inversely proportional element.

As you advance timing, cylinder component temperature rises and EGT falls.

AS you retard timing, cylinder component temperature falls and EGTs rise.

As A/F lowers, both cylinder component temps and EGTs fall.

As A/F raises, both cylinder component temp and EGTs rise.

This is a crude and simple explanation of events, but it reflects what I am saying:

When you can't change the boost, to make a safer configuration will be to drop the A/F and the timing together. The drop in power will also notify the driver it is in safety mode.
