It's just for that ONE particular module installed in your ship. However, you can then un-mount that module and install it on another ship. If I understand the grind correctly, you will work on, say, Elvira Martuuk and get her to make top tier FSD mods for you, so you grind tier 1-5 or something like that. After that initial grind, the next FSD you want to mod, you're straight at tier 5. Someone correct me if I'm wrong here?
