Hey there,

I'm trying to add a custom upgrade to a part (SSTU's Soyuz), and so far it works in adding an extra crew slot, but I have hit an unexpected snag: Resource amounts don't seem to be upgraded when the upgrade is unlocked.

Or if it's impossible, any workarounds?

Here's my config:

Look in the Module Manager cookbook and try to find some stock configs using this node for a template to use. 

The KSP API has info on the node values, look at the Public Attributes list here: https://kerbalspaceprogram.com/api/class_part_upgrade_handler_1_1_upgrade.html

Looked around the docs (Both the ModuleManager handbook and the KSP API), and can't see anything that (directly) jumps out as a way to add resources via upgrades. I could just be blind to it ._.

Hahaha!

Well sort of, I found these:

Also you can download the Porkjet replacement parts, those have some upgrades that you can use as an example.
