Alright fixed it, I just reloaded an old save before I installed the atomic surgery mod. I have no idea what happened, but it's fine now.

Just gave her a pocketed metal arm and a backpack, her carry weight is still capped at 11 pounds. -- However I gave myself the Inspirational Perk and it did increase her carry weight. She can now carry ~41 pounds. I'm gonna play around with some console commands some more and see if that fixes it. At least I know her weight can be changed now.

Just finished a hard troubleshoot. The mods aren't effecting it. I think it might be a save issue.

I just got Cait and when I try to give her some of my stuff she becomes overencumbered after 11 pounds or so. -- What I tried so far to fix it that failed: I tried disabling all my companion mods for Cait. I tried using the command "forceav carryweight 270". I tried to change the base weight modifier in the game and the strength modifier. I tried using the command "forceav strength 7". -- I'm stumped guys, I'm going to try to do a hard troubleshoot. But I would greatly appreciate some help.
