The Stage 3 Power Package includes the COBB Accessport with PDK Flashing, CSF Intercoolers, Akrapovic Titanium Link Pipe Set w/ Cat & Titanium Slip-On Line Exhaust Tips.

The handheld Accessport V3 has a large, full color, higher resolution screen which allows you to monitor up to six parameters in real time. Fully customizable from the look (multiple bezel colors), layout (set up a race, street or dyno gauge cluster) and mounting options (choose from 1,000s of standard vehicle mounts). Of course, all of the great COBB tuning is included - with enough space for 100 calibrations. This is your new Accessport - and maybe the last one you'll ever need.

All Performance Maps are pre-loaded on the Accessport.

Made from titanium and designed to create a better and smoother exhaust flow, the Akrapovic Link Pipes with 100 cpsi high-flow catalysts are the next step in the tuning process and can be easily installed with the Slip-On Line system. Giving further weight savings over stock—when used in conjunction with the Slip-On—the combination of this pairing highlights the exceptional character of the Porsche boxer twin-turbo engine. The improvement in performance is further enhanced by the unique sound the Akrapovic engineers have produced. The distinctive roar from this superb engine gets noticeably louder and more complete as the revs rise, without creating an uncomfortable noise in the cockpit. To complete the quality finish, the surface of the link pipes is treated with a coating to increase durability, without changing the appearance when upgrading an Akrapovic exhaust system with the link pipes.

The Akrapovic Slip-On Line for the Porsche 911 Turbo / Turbo S is the first stage in the exhaust tuning process and gives this already outstanding car a further step in performance. Made from a high-grade titanium alloy and finished with exquisitely handcrafted carbon fiber and titanium tailpipes, the Slip-On Line reduces weight to aid in handling. Akrapovic’s sound engineers have also created a deep and unique sound to make the Porsche 911 Turbo / Turbo S stand out even more.

CSF Cooling is proud to announce the official public release of its Porsche 991 Turbo & Turbo S high performance intercoolers for both 991.1 & 991.2 models. Since the intercoolers made their official world debut at the 2017 SEMA show, a unique sales decision was made to only release these intercoolers (for a period of 1 year) to a select group of the world’s most highly regarded Porsche motorsport ECU tuners and vehicle builders. Over the past year, CSF’s Porsche 991 Turbo intercoolers have been race-tested, logged, and fully validated by some of the world’s best Porsche tuners. These intercoolers have been regarded as the “Go-To” option for the best performance and value available in the performance aftermarket.

Validation of CSF’s Porsche 991 Turbo Intercoolers started with a GMG Racing modified vehicle with typical bolt-on modifications and a stage-1 tune. Extensive dyno testing was completed over a 4-day period with similar ambient air temperatures in a controlled dyno cell and were conducted at similar times in the day (Early morning and afternoon to control air density variability). These tests consisted of several real-world test simulations with data proving a massive increase in performance and heat rejection of the CSF Porsche 991 Turbo Intercoolers.



The Accessport V3 is the world's best selling, most flexible ECU upgrade solution for Porsche. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Upgrade forever with off-the-shelf (OTS) calibrations for most bolt-on modifications. It's the last engine management solution you'll ever need.

Porsche 991 Turbo PDK

  • Increased Minimum Shift Points
    • This feature increases the lowest RPM at which the PDK will shift to the next gear in Normal and Sport drive modes.

Normal Mode:

Sport Mode:

Increased Auto Shift Points

  • This feature increases the highest RPM at which the PDK will shift to the next gear in Normal, Sport, and Sport Plus drive modes.
    • 991 Turbo
      • COBB Sport increases the auto shift limit to Turbo S factory shift RPM.
      • COBB Aggressive and COBB High Torque Aggressive maps increase the auto shift limit to a maximum of 7400RPM.
    • 991 Turbo S
      • COBB Sport does not increase the auto shift limit on the Turbo S.
      • COBB Aggressive and COBB High Torque Aggressive maps increase the auto shift limit to a maximum of 7400RPM.

  • Race Start Lite:
    • This adds Race Start to Porsche Normal and Sport drive modes for all cars (including vehicles that do not have Sport Chrono). In COBB Sport, COBB Aggressive, and COBB High Torque Aggressive maps Race Start Lite is set at 4500RPM in Normal and Sport drive modes. Race Start in Sport Plus remains at the factory 5500RPM.
  • Increased Shift Firmness
    • COBB Sport, COBB Aggressive, and COBB High Torque Aggressive maps raise the shift firmness to help reduce clutch slip.
  • Increased Clutch Pressure
    • COBB High Torque Aggressive maps raise the maximum clutch pressures to help reduce clutch slip after shifting. The COBB High Torque Aggressive map is typically used on vehicles that have an increased engine torque output of 50% or more over stock. If the COBB High Torque Aggressive map is flashed to the TCU a PDK Relearn must be completed when changing maps back to COBB Sport, COBB Aggressive, Simulated Stock, or when uninstalling. Failure to do so may result in less than desirable shifting and/or TCU errors. PDK Relearn instructions are located below.
  • Minimized Continuous Clutch Slip
    • COBB Sport, COBB Aggressive, and COBB High Torque Aggressive maps decrease the RPM at which the clutch is engaged in continuous slip, generally between 1000-2500RPM.
  • Summary
    • COBB Sport: Increased minimum shift points, Race Start Lite enabled, shift firmness increased, and continuous slip decreased.
    • COBB Aggressive: All COBB Sport features plus increased maximum shift points.
    • COBB High Torque Aggressive: All COBB Sport and COBB Aggressive features plus increased clutch pressures.
