    • Porsche 991.2 GTS with cat bypass and custom dyno tune - 470 rwhp

      This is your basic tuning recipe for a Porsche 991.2 9A2B6. That means a dyno tune and bypass pipes or downpipes as some call them. The majority of 991.2 twin turbo 3.0 flat-6 models will not go beyond this level of tuning.


      The results on Florida pump gas in warm weather are respectable:


      The power curve holds well but they do not rev it out past 7000 rpm.

      Hydra Motor Works did the tuning and they certainly do better on factory turbo cars than turbo upgraded examples.

        I made similar power on my car on COBB stg.1, BME filter and AWE 200cell sport cats. I'm guessing theres marginally more peak hp, but theres definitely more power under the curve with the stg. 2 software I'm currently running.

        I would think there's more on the table with a custom tune, but perhaps headers are needed and the testing conditions are playing into it.

        I’d like to see inlets and sports cats. Prolly more than 470WHP
