The corrections are for when EGR is applied, so if it's application is
disabled, like setting the min temp to 254, it is invisible.

Just might stop there and look at doing a 1227730 install rather then the
165.

GMWPro, and TunerCat I beleive both sell 6E mask editing software.  Dunno
off hand how much EGR editing is in that one thou.
