Porsche 982 718 Cayman/Boxster GTS 4.0L Calibration Notes

 

Stage Hardware Requirements

  • Stage1 - Designed for a vehicle with the following modifications:

    • Headers: Stock

    • Exhaust: Stock

    • Air Filter: Stock or aftermarket drop-in filters

    • Fuel System: Stock

  • Stage2 - Designed for a vehicle with the following modifications:

    • Exhaust: Aftermarket OAPs and/or aftermarket headers

    • Air Filter: Stock or aftermarket drop-in filters

    • Fuel System: Stock

Minimum Octane Requirements

  • ACN91 Octane - For use with ACN91 octane (R+M)/2 or 95RON fuels minimum. 94 octane fuels with 0% Ethanol should also run the ACN91 octane file.

  • 91 Octane - For use with 91 octane (R+M)/2 or 95RON fuels minimum. 94 octane fuels with 0% Ethanol should also run the 91 octane file.

  • 93 Octane - For use with 93 octane (R+M)/2 or 98RON fuels minimum.

  • 100 Octane - For use with 100 octane (R+M)/2 or 105 RON fuels minimum.

  • E85 - 70% ethanol minimum

*Warning*

Using a lower octane than is designated by the calibration can promote increased engine wear and in severe cases catastrophic engine damage. Never run a map designed for high octane with low octane in the fuel tank. E.g. Do not run the 100 Octane map with 93 octane fuel in the tank.

Torque and Horsepower Output

These dyno charts represent typical power output to the wheels as tested on a Mustang dynomometer.

  • “Max Gain” represents the largest delta between any two points on the graph at the same RPM.

  • “Peak Gain” represents the overall delta of the highest reading per dyno plot.

  • We break up power gains into % and numerical gains. We know that every dyno reads a bit different, particularly between manufacturers, so we have utilized the percentage gains which should be similar and independent of the dyno. The numerical delta gains are a more user friendly value but may not read similar on every dyno.
