Simple ECU flashing with gauge package! The in-cabin mountable Accessport V3 has a large, full color, high 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 race, street, or dyno gauge clusters), and mounting options (choose from 1,000s of standard vehicle mounts). And what's looks without brains? More processing power, memory, and storage to flash faster while saving all of your maps and logs. This is your new Accessport.

Warning! Installation of this Accessport over anything other than OEM or COBB software may result in ECU/TCU failure. Please contact COBB Support if you have any questions.

EQT Power Estimates

This is a question asked all too frequently, and while we’d love to give you a specific number, there are many variables involved that can affect dyno results. Even taking the car’s modifications out of the equation, there are other variables such as weather, elevation, fuel quality, dyno type, dyno fan setup, etc. that come into play. With that being said, these are ranges that most vehicles will see, given standard modifications and reasonable conditions:

  • Stage 1 GTI -
    • 91 AKI: 300-310whp / 360-380wtq
    • E85 Low Torque: 330-350whp / 360-380wtq
    • E85 High Torque
  • Stage 2: GTI - In Testing
