Off The Shelf Maps & Power Gains

Included in the Accessport, also available for download on our website, are our COBB Off The Shelf (OTS) Maps.  These files are generated by our COBB Calibration Team for otherwise stock cars.  Components like replacement air filters for the stock airbox and exhaust components that retain factory catalytic converters are safe to use with these OTS Maps.The Stage0 file does not increase power as it retains all factory calibration data but provides the ability to utilize all of the other Accessport functions, such as data monitoring and logging.

Our OEM+ file for the standard 992 S model utilizes calibration data derived from the GTS trim vehicles as they are mechanically identical and simply use tuning to manipulate power output differential.  Our Stage 1 files are aimed at really taking advantage of what Porsche has left on the table.  With increased boost pressure and more aggressive timing/fueling curves, and much more, we are able to produce a significant increase in both low end torque as well as top end power.

  • Stage0 v100
  • OEM+
  • Stage1 91 OCT or 95 RON v100
  • Stage1 93 OCT or 98 RON v100

  1. How are the S and GTS results different? The hardware is exactly the same. The factory tune is just a little different.

    • Hey there! You are correct, the S & GTS are identical apart from software/calibration data. That holds true for the transmission (PDK) programming as well. The difference here is that the GTS transmission programming allows for the motor to make a bit more power than the S. We plan to investigate PDK tuning for 992 vehicles in the future.


    • Hey there! We haven’t had a MY24 car in yet to check. We’ll likely have a bit of work to do in order to add support for those.
