    • Shiftech 2019 971 Porsche Panamera 4S 2.9 EA839 ECU flash tune results - 530 horsepower

      The Audi EA839 V6 architecture is going to be a big deal not just for Audi models but many Volkswagen Auto Group brands. For example, the 971 generation Porsche Panamera 4S utilizes the EA839 2.9 V6 architecture which is shared with the Audi B9 RS4 and RS5 models.


      That means shared aftermarket development in many respects although things do diverge. The Panamera routes its output to all four wheels through a PDK dual clutch transmission and not an automatic like the RS4/RS5 for example.

      The 2019 Panamera 4S is rated at 440 horsepower stock. Uncorrected, that is about right on the money according to the Shiftech baseline.

      So what does it pick up with Stage 1 pump gas ECU flash? 66 horsepower at all four wheels or peak output goes up to 526 PS:


      Shiftech claims 530 horsepower which is accurate depending on fuel quality.

      Notice torque goes up to 545 lb-ft from 430 lb-ft. A very, very nice software only increase.
