My brothers D1 has EGT and boost.
my D2 as of today has EGT, boost, and trans temp. The water temp gauge was on back order but has been posted and I've already run power for it.

I took trans temp temp from the trans directly, there is a plug right next to the hot cooler line. It's M15x1.5 and I simply used an M14 to 1/8 npt adapter and put the sensor there. It responds quite quickly.
