Maybe bump up production module from 20% to 25% - I would love it to be bumped even more like to 27% or 30%, but then calculating stuff from my head would be a headache.

The quality module I suggest you to bump to 7.5% - it would be a tripple of the vanilla game. Quality in vanilla is rather pain to work with, so making it that much easier would be really nice/worth it.

Efficiency module could be 100% - simply double, instead of 90% (what was the reason for this, when other ones are double of the vanilla T3?)

I'm not sure if efficiency modules can be 100% or if it might throw the game's math off. For the other modules I gave them values that felt right, considering you can also upgrade them to higher quality tiers too.
