What does the Performance module do?
It depends on the machine: printer speed in a 3D Printer, growth rate in a Hydroponic System, attractiveness in a Mirage Projector, and nothing in a Furnace.
Probably Stolen Modules Guide
Modules slot into machines and have three stats: Performance, Efficiency and Quality. What each stat does depends on the machine, and each machine's manual lists it under "Module Impact". Efficiency always lowers power consumption; Performance and Quality change something specific, such as a printer's speed or a purifier's maximum purity.
Probably Stolen modules: the short answer
For what the game is and every guide we publish, start at the Probably Stolen guide hub.
- Read the manual: the table below collects every machine's Module Impact.
- Watch placement: some modules get bonuses from where they sit in the module bay or what is next to them.
- Stuck module? You need a Module Extractor to take it out without breaking it.

What Performance, Efficiency and Quality do
Every module has the same three stats: Performance, Efficiency and Quality. They don't mean the same thing in every machine. Each machine's manual has a "Module Impact" section that says what each stat changes there, and in some machines a stat only counts at a ratio, for example "Performance (0.25 Ratio): Attractiveness".
The general-purpose modules are named Performance Module, Efficiency Module, Quality Module, Overclock Module, Eco Module, Refinement Module and Streamlining Module. The game doesn't describe what the last four add beyond their names, so check a module's stats before you fit it.

What modules do in each machine
| Machine | Efficiency | Performance | Quality |
|---|---|---|---|
| Furnace | Power consumption | No effect | Maximum purity |
| Mirage Projector | Power consumption | Attractiveness (0.25 ratio) | Attractiveness (0.5 ratio) |
| 3D Printer | Power consumption | Printer speed | Print quality on eligible items (0.25 ratio) |
| Hydroponic System | Power consumption | Growth rate (0.5 ratio) | Max yield % (0.5 ratio) |
| Moisture Farm | Power consumption | Volume produced | Purity |
| Water Purifier | Power consumption | Amount removed per night | Maximum purity (0.5 ratio) |
| Evaporator | Power consumption | Volume evaporated per night | Volume of vapor captured |
| AgeWell | Power consumption | Power consumption | +1 day of age per 125 Quality |
| Alarm | Power consumption | Prevention rate bonus | No effect |
| Cryptographic Desequencer | Power consumption | Speed | No effect |
Two quick reads of the table: Performance does nothing in a Furnace, so fit Quality there for purer ingots; and in an AgeWell, Quality is the only stat that adds aging. What each machine does is on our machines guide.
Module traits and placement
Modules can carry a trait that changes their stats. The game lists ten:
| Trait | What it does |
|---|---|
| Premium | Higher base stats, but costs significantly more |
| Inferior | Lower base stats, but costs significantly less |
| Overcharged | Higher base stats, with a chance of being permanently ruined on use |
| Degrading | Starts with double the base stats but loses some each time it is used |
| Learning Algorithm | Starts with no positive stats and gains some each time it is used, up to a maximum |
| Top Mount | A temporary bonus if it touches the top edge of the module bay |
| Side Mount | A temporary bonus if it touches the left edge of the module bay |
| Receiver | A temporary bonus for each adjacent Node |
| Support Node | Gets a share of each adjacent module's base stats as a temporary bonus |
| Negative Feedback | Higher positive base stats, but takes on some of the negative stats of adjacent modules |
So where you put a module in the bay matters: mounts want an edge, and Receivers, Support Nodes and Negative Feedback modules care about their neighbours.
Machine-specific modules
Some modules only work in one kind of machine:
- Furnace: Furnace Module (Blast) lets more materials make more Metal Ingots at slightly lower purity, and doesn't stack; Furnace Module (Junk Processing) turns Junk into Scrap Metal.
- 3D Printer: the Metal Printer Module lets it use metal printer chips; the Computer Numerical Control Module, together with metal printing, lets it use gun frame and gun part chips; the Melee Batch Module adds one more weapon to every melee print.
- Hydroponic System: seven modules, among them the Hydroponic Smuggler Module, which removes the contraband status of growing seeds, and modules that change Dream Cap, Hydroreed, Fillerweed, Nutrifruit and Kotton harvests.
- Evaporator: the Solvent Recovery Module only recovers solvent.
- Alarm: the Alarm Transmitter Module gains reputation each night with the faction it transmits to; transmitting twice to the same faction has no extra effect.
- Chemistry: the Chemical Equipment Module improves the Blender, the Heating Plate and the Chem Finisher, and needs a Module Extractor to remove once installed; see chemistry tools.
- DNA Manipulator: Genetic Stabilizer, Positive Trait Filter, Negative Trait Filter and Precision Extraction modules.
Removing, repairing and adding module slots
- Stuck modules. A module can show "[Stuck. Requires a Module Extractor.]". The Module Extractor (Basic) takes stuck modules out without breaking them, has a limited number of uses and can be partly refurbished with Electronic Parts. The Module Extractor (Advanced) does the same and doesn't wear out.
- Corrupted Module: can be restored with Electronic Parts "and a little know-how".
- Ruined Module: still has salvage value and can be broken down with a Screwdriver.
- Blank Module: "With the right machine, this could rewrite this into something useful."
- More slots. A Module Bay Expansion Kit expands a machine's module capacity once. It doesn't work on chemical or other special machines.
The Probably Stolen Cryptographic Desequencer and modules
The Cryptographic Desequencer is one of the machines that take modules: Efficiency lowers its power consumption, Performance speeds it up, and Quality has no effect. It writes keycards overnight from a Desequencer Chip and an access keycard. How to use it on locked crates is on our lockers guide.
Version notes and limits
This page doesn't give module stat values, the percentages behind each trait or how many uses a Basic Module Extractor has; the game shows those per module rather than as general rules. It also can't say what Overclock, Eco, Refinement and Streamlining modules add. We will update it if a patch changes modules.
Probably Stolen modules FAQ
What does Efficiency do?
It lowers power consumption in every machine whose manual lists it.
Which module should I put in the Furnace?
Quality: in a Furnace it raises maximum purity, while Performance has no effect.
How do I remove a stuck module?
Use a Module Extractor. The Basic one has limited uses; the Advanced one doesn't wear out.
Can I add more module slots?
Yes, with a Module Bay Expansion Kit, once per kit, on machines that aren't chemical or other special machines.
Does module placement matter?
For some traits, yes: Top Mount and Side Mount modules want an edge of the bay, and Receiver, Support Node and Negative Feedback modules depend on their neighbours.
