I'm not sure if it's the mod or the Direwolf20 1.7.10 FTB pack but my armour is not getting the power values it should according to the tutorials I've seen and the Ender IO website. Maybe the FTB team can override things outside of the endio.cfg file?

I checked the enderio.cfg file and the values looked correct. I deleted the config file updated the pack and the same problem still existed.

Here a couple of pictures:
