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 "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.

Results may vary. Power as tested on 2010 Porsche 911 (997.2) GT3






Non Performance Maps:

Valet Mode

  • Rev limiter set to 4000 RPM.

Anti-Theft Mode

  • This map will not allow the vehicle to start.

Stage 0

  • Stock calibration. No changes made at all.

    • NOTE: Stock and OTS maps are not compatible with iPE Exhaust systems.





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 fall outside of OTS map requirements.
  • Top Tier gasoline should be used where 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.
