Map Availability:



  • 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.


    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 


Stage 1

  • Exhaust Requirements: Stock
  • Intake Requirements: Stock air box with stock, or upgraded Air Filter
  • Boost Target:
    • 91 Octane (95 RON Minimum): 18 psi +/- 2psi tapering off to redline
    • 93 Octane (98 RON Minimum): 18 psi +/- 2psi tapering off to redline


Peak Gains are reported as the absolute maximum value (HP and TQ) between the highest points of two plots.
Max. Gains are reported as the maximum TQ or HP gain at any point across engine speed range. 


Dyno results and gains are from first party testing on external dyno and blended 93 octane due to lack of vehicle and fuel availability to COBB for in house testing.

Non-Performance Maps

Stage 0

  • Stock calibration. Factory map. Does Not Uninstall Accessport.




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.
