I don't exactly know how Tremor mod is structured on that regard, but I'd say they'll most likely both work independently (and I don't believe you'd want to have two different hunger systems running independently from each others). I don't know whether you can disable Tremor mod's hunger system, but once I'm done with thirst, I'll make it so you can disable the individual features from this one, so you could possibly have the thirst from this mod, then hunger from Tremor (altho again, they will not have any way of knowing each others exist and will work independently, but at least they will not cover the same feature).
I'll point this out however, if
@zadum4ivii wishes to, I'd be perfectly fine with trying to work a way around it to reduce conflicts or ensure cross compatibility, this mod was made with the purpose of being a core system other modders can hook to.
