Now we can offer two performance stages for the current Porsche 911 991 Carrera 4 GTS with 3.0-liter turbo engine. Both stages offer a significant performance increase for more driving pleasure. The stock power of 450 hp and 550 Nm raises up to 475 hp and 570 Nm by stage 1 software optimisation. At the stage 2 performance upgrade, we install in addition to our software also a flap exhaust system with sport catalysts made by Capristo with the result of 485 hp and 585 Nm. Of course, in combination with a great sound that can be adjusted as needed by radio remote control.
