I believe a matter of personal preference. I have mine with the boost up top/closest, then EGT then tranny temp. Just the way I like to look at it. Others will differ, but I know the boost cost me some serious fuel economy as I tried to swing it every time when I first installed it. Now I look more at my EGTs on a regular basis but still watch the boost. The tranny thing has not been a huge issue as I don't tow heavily and it rarely moves much, but I still glance occasionally just to be sure it works.
