This isn't a generic flash. Our 981 Boxster and Cayman 2.7 flat-six calibrations are developed in-house, optimized on the dyno, and tested on the street and track. Every map is built around your fuel, your hardware and how you actually drive the car — real gains with factory-level refinement and reliability.

Estimated on a healthy car with known-good fuel:

  • 261 hp → 286 hp — estimated gain of +25 hp
  • 207 lb-ft → 237 lb-ft — estimated gain of +30 lb-ft
  • Fuel maps available for 91, 93 and 100 octane
  • Sharper throttle response and revised rev limits
  • Calibrated for consistent performance in all conditions

The 981 Boxster and Cayman in base form run the 2.7L naturally aspirated flat-six. Be realistic about what a flash does on a naturally aspirated engine: there is no boost to raise, so the gains come from ignition timing, fuelling, throttle mapping and rev limits. The figures above reflect that honestly. On the 2.7 the torque gain matters more than the headline horsepower — this is the engine that feels thinnest in the mid-range from the factory, and that is precisely where the calibration puts the work.

What's included:

  • Custom ECU calibration developed around your fuel, hardware and driving preference
  • Optimized ignition timing, fuelling and rev limits for your specific car
  • Throttle response and drivability refinement
  • Fuel map matched to the octane you actually run — 91, 93 or 100
  • OBDII data cable shipped to you
  • Same-day file turnaround once we have your stock read

What we need from you:

  • Your factory stock file, read with the cable we send you
  • A complete list of current modifications
  • Vehicle details and VIN
  • An honest description of the car's mechanical condition and service history
  • The octane you run day to day

Supported Vehicles:

  • Porsche Boxster (981) — 2.7L naturally aspirated flat-six, 2012–2016
  • Porsche Cayman (981) — 2.7L naturally aspirated flat-six, 2012–2016

How to order:

  • 1. Order online. We ship you an OBDII data cable — typically 2–3 days to arrive.
  • 2. Read your stock file. Plug the cable into your OBD port, upload your factory file, then email it to us with a list of your current modifications.
  • 3. Get your file back the same day. We email your custom calibration back the day we receive your stock read — and we'll make sure you're happy with it.

Before you order:

  • Power figures are estimates, not guarantees. Results vary with fuel quality, altitude, ambient temperature, mechanical condition, supporting modifications and dyno methodology.
  • Mechanical condition — tuning raises cylinder pressure and driveline load. The car must be sound first. Pre-existing faults revealed or accelerated by tuning are not our responsibility.
  • Accurate information required — we build the file from what you tell us. An unmodified stock read and an honest description of the car, its modifications and its condition are required.
  • Warranty — an ECU modification will likely void any remaining factory powertrain warranty.
  • Legal use — certain calibrations are for off-road and competition use only. Compliance with federal, state and local emissions law is the buyer's responsibility.
  • Risk and liability — the customer assumes the risk of modification. Our liability is limited to the price of the tuning service.

Note: Tuning services are non-refundable once the file has been delivered. The service is complete at delivery. Full terms are on our Terms of Service page.
