M-Engineering Calibration for the 991 GT2RS

Looking to unlock a lot more power in your 991 GT2RS? The team at M-Engineering are without a doubt, the best in the business at just that. Having worked with both PMNA (Porsche Motorsport) and MSO (Mclaren Special Operations), no one has more knowledge, or more ability than them. We run their calibrations in our personal track cars and have many track only GT3's and GT2's running their same calibrations.

We strongly suggest CSF intercoolers for track cars using this calibration.

Custom Feature Package Includes: Calibration, Map Switching and PDK Tuning

• Live Map Switching
  • Map Switching allows the driver to independently select power levels based on the octane of the fuel or fuel type by using the cruise control stalk. Map switching can be performed with the vehicle running without the need to shut the engine off.
    • Example Map Slot Setup:
      • Slot1 - Stock Power
      • Slot2 - 93 Octane
      • Slot3 - 100 Octane
      • Slot4 - E85
      • Slot5 - Valet
    • Since Map Switching can be customized depending on the individual please contact us when purchasing if you'd like a different setup or would like a custom map slot.
