I saw a video stating that a pre-req for the DFC90 is an Entegra systems with at least version 8.x and a MOD 55 hardware upgrade.

Can someone clarify this? How can I be sure that my system has this mod?

To see if the PFD has MOD 55, you'll have to look for the corresponding mark on the TSO label on the back of the unit. If it does not have MOD55 marked, you'll have to RMA the unit to have the mod applied. The latest software would be installed at the same time.
