Supported Vehicles:

  • 2017-2019 Porsche 911 (991.2) Turbo PDK WM
  • 2017-2019 Porsche 911 (991.2) Turbo S PDK WM
  • 2018 Porsche 911 (991.2) GT2 RS

  • Porsche 911 Exclusive Edition (Supported by the Accessport however it will require custom maps and we do not offer OTS maps for this vehicle at this time.)


Map Revision: 



Turbo, Turbo S

  • Stage0 v107
  • Stage1 v107


2018 GT2 RS

  • Stage0 v107
  • Stage1 v107


Required Accessport Firmware: 

  • AP3-POR-012: 1.7.3.1-16957 or greater




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.

Stage 1 

  • Exhaust Requirements: Stock
  • Intake Requirements: Stock air box with stock air filter


Peak Gains are measured as the absolute maximum value 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 that the car was delivered from Porsche with. 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 Turbo 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.
