Package

This isn't a generic flash. Our Panamera S and 4S 4.8 V8 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:

  • 394 hp → 420 hp — estimated gain of +26 hp
  • 370 lb-ft → 400 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 970 Panamera S and 4S run the 4.8L naturally aspirated V8. 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 — a worthwhile sharpening of how the car responds rather than a transformation. The torque gain is the part you actually feel, particularly in the mid-range where a heavy four-door spends most of its life. This calibration covers both the rear-wheel-drive S and the all-wheel-drive 4S.

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 Panamera S (970) — 4.8L naturally aspirated V8, rear-wheel drive, 2009 to current
  • Porsche Panamera 4S (970) — 4.8L naturally aspirated V8, all-wheel drive, 2009 to current

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.

In the Southern California area? Get in touch and we can tune your car in person instead.

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.
