Map Availability:
- Download from the COBB Tuning Porsche Map Database
Hardware Requirements:
Stage2 requires an exhaust system in order to be used. Intercoolers are recommended on any stage to combat high intake air temps on the Porsche.
Stage3 1000 requires an exhaust system, Cobb1000cc fuel injectors(Discontinued), and upgraded intercoolers.
Stage3 1300 requires an exhaust system, Cobb1300cc fuel injectors, and upgraded intercoolers.
Fuel Requirements:
Each map lists the minimum required octane. A higher octane fuel can be used safely on a map designed for lower octane. DO NOT use maps designed for higher octane with lower octane fuels. Top Tier gasoline should be used where available.
- Maps designated with "100" are for use with 100 octane/104 RON fuel or better.
- Maps designated with "93" are for use with 93 and 94 octane/98 RON fuel or better.
- Maps designated with "91" are for use with 91 and 92 octane/95 RON fuel or better.
- Maps designated with "ACN91" are for use with 91 octane fuel found in Arizona, California, and Nevada or better.
- Maps designated with "E85" are for use with 85% Ethanol, 15% Gasoline fuel only.
These maps are designed for E10 fuel (fuel with 10% ethanol content). For those who only have access to E0 fuel (fuel with 0% ethanol) it is recommended to use the "91" and "ACN91" octane versions of the maps and datalog the car to ensure your fuel is performing to the necessary level. This is especially important for those using Canadian 94 octane E0 fuel.

Stage1
- Exhaust Requirements: Stock
- Intake Requirements: Stock air box with stock air filter
- Boost Targets:
- High Flow Exhaust (larger diameter piping)
- High flow catalytic converters.
- *Stage 3 Maps are available here via Cobb Tuning's Website.
- Exhaust Requirements: After-Market Exhaust System
- High Flow Exhaust (larger diameter piping)
- High flow catalytic converters.
- Intake Requirements: Stock airbox with stock air filter or upgraded panel filter.
- Cobb 1000cc Injectors (Discontinued)
- Use Stage3 1000 ... v103 maps.
- Cobb 1300cc Injectors
- Use Stage3 1300 ... v103 maps.
- Upgraded Intercoolers
Non Performance Maps
Valet Mode
- Rev limiter set to 4000 RPM. Not for use with Stage3. Boost lowered to half of normal.
Anti-Theft Mode
- This map will not allow the vehicle to start.
Stage 0
- Stock calibration. No changes made at all.
Closing Warnings and Precautions:
- Use of inappropriate calibration/modification combinations will promote engine damage
- Seek the help of a professional COBB Protuner should your Porsche Turbo fall outside of OTS map requirements.
- Top Tier gasoline should be used when available. Use of lower quality fuels can result in catastrophic engine damage.
- For track events, we recommend adding at least 2 gallons of 100 octane fuel to battle high track temperatures.
If using E85 it is your responsibility to ensure you are getting the proper mixture from your station. Many stations change to an E70 blend in the winter.

Revision Notes:
V103:
Revision Notes:
| Map Version | Notes: |
|---|---|
| v105 | Updated maps to correct odd throttle/torque behavior unique to B742 ROMs only. All 997.1 Turbo maps updated to v105 for conformity, but B721, B730, B740, B821, and B830 maps are unchanged from V104. |
| v104 | Map description fixes. |
| v103 | Updated maps to add factory fuel PID oscillation issue |
fix | |
| v102 | Updated maps to correct a factory fuel PID oscillation issue unique to B742 ROMS. All 997.1 Turbo maps updated to v102 for conformity, but B721, B730, B740, B821, and B830 maps are unchanged from V101. |
| v101 | Improved map stability and map maintenance update for future feature support. |
V100:
| v100 | Adjusted load correction, load and torque limits, raised vehicle rev limits, raised vehicle speed limits, brake boosting enabled for 2 seconds. Also increased boost in both normal and sport modes. Made fueling changes as well as timing changes and raised the timer for sport mode to 30 seconds. |
