    • 2014 Porsche 991.1 Turbo S Cobb V3 Accessport Johnson Tuning Protune only results - 570/637

      Great to see some tune only numbers on a Porsche 991.1 Turbo S from an all wheel drive Dynojet. Johnson Tuning did a custom tune for this 2014 911 Turbo S through the Cobb Tuning V3 Accessport system.


      The result is some very healthy gains over the baseline of 525 horsepower at all four wheels:


      Peak horsepower increases almost 50 awhp but the torque figure is where the real boost happens.

      The stock figure of 545 lb-ft at the wheels increases to 637 lb-ft at the wheels. The only problem? Where is the torque curve on the graph?

      No reason to doubt Johnson Tuning but with turbo motors we definitely want to see the torque curve.

        The plot has MPH on the X-axis, so they probably couldn't get an rpm signal. No rpm signal, no torque curve. Easy enough to back out the torque though if you know what gear the car was dyno'd in.

        Yeah that is probably why but man I prefer having that torque curve on the graph.

        I think this is an issue with people who haven't upgraded their Dynojets for a new sensor or something? Not sure what it is but I think @quattr0 had this problem when getting dyno'd.

        I think it is an adapter/plug for older dynojet. They could still read without it by connecting to the ignition coil wire but would require cutting the wire loom cover the engine and tape it back. That was on .2 tho. Not sure if same for .1.
