PERON Tuning Stage 2 ECU Calibration for Porsche 991.2 GTS (3.0T)

As with all major developments at PERON Automotive, our Stage 2 calibration for the Porsche 991.2 GTS is the culmination of months of dedicated work by our highly skilled engineers in PERON's world-class facility. Although the 991.2 GTS is already an extraordinary vehicle, we approached its 3.0T engine with a specific goal: to enhance performance without compromising its balance or factory-like driveability. Throughout an extended development process, we meticulously worked with the Siemens SDI21 ECU to achieve significant performance gains while retaining the smooth, linear power delivery that defines the GTS.

Enhanced Driveability and Performance

Our Stage 2 package for the Porsche 991.2 GTS delivers impressive power gains, boosting output to 560-580 hp and 490-510 lb-ft of torque on 99 RON fuel. This upgrade not only increases responsiveness and peak power but also preserves the car’s mid-range torque and top-end crescendo, ensuring a faster, more exhilarating driving experience without upsetting the chassis balance. The result is a seamless increase in speed with smooth, controlled power delivery.

Fuel Requirements and Efficiency
This tuning stage is optimised for 99 RON fuel, although it remains effective with 97-98 RON. The Stage 2 calibration provides significant power increases while maintaining fuel efficiency, ensuring that your GTS delivers performance without sacrificing its everyday practicality.

Hardware Requirements

  • Akrapovič Slip-On Line (Titanium)
  • Akrapovič Link Pipe Set w/ Cat (SS)
  • New set of factory Porsche 991.2 3.0T spark plugs (recommended if the vehicle hasn’t been recently serviced)

ECU Tuning Highlights for the Porsche 991.2 GTS

  • Torque and Load Management: Improved internal calculations enhance power distribution, offering better drivability and control, especially under hard acceleration.
  • Boost Control Refinement: Boost pressure adjustments provide quicker turbo response and more consistent power delivery, leading to improved acceleration and overall driving dynamics.
  • Fuel Delivery Optimisation: Fine-tuned fuel flow and increased cylinder pressure ensure safe, reliable performance under high loads, supporting increased power without compromising engine longevity.
  • Lambda Optimisation: Optimised air-fuel ratios ensure efficiency and safety at higher power levels, delivering smooth and consistent performance across all driving conditions.
  • Ignition Timing Optimisation: Precise ignition timing adjustments boost power, enhance engine smoothness, and improve fuel efficiency while safeguarding the engine during high RPMs and aggressive driving.
  • Rev Limiter Increase: The raised soft limiter in neutral enhances the exhaust note during stationary revving, delivering a more engaging and thrilling auditory experience.
