Based on everything on the product website, this is a throttle remapping device, meaning it takes in the position of the accelerator pedal and passes it to the car's computers with a change. Essentially it changes your throttle response to your foot. So for example it may lower your acceleration unless you really jam the pedal. It can take into account how fast you're pressing the pedal too. This can give you throttle response you prefer (personal preference). This may give you better battery life by the pure virtue that it will limit how quickly you accelerate (akin to range mode). It will not give you higher max acceleration or power, since 100% throttle is 100% throttle (unless Porsche ECU has a bug and will accept values above 100% which the accelerator pedal would never give, but if that is the case, you may be stressing the battery and/or motors beyond their design envelope).I had my 4S for a bit before I purchased the Race Card Chip.
You can feel it when you start your app on the phone and it Connects to the car. Better acceleration then normal, Better Battery life depending on what Mode you put it on.
You have 3 Modes to choose from.
Sport
Comfort and
Economy mode.
Some people different throttle mappings, which is why some Tesla driver's prefer to drive in "chill mode" which limits their acceleration unless they floor the accelerator, making the ride less "jerky". I think Porsche also changes throttle response based on driving modes. I don't have mine yet, but remember from the test drive that switching to SportPlus the throttle became a lot more responsive.
So for you the value of this device is that it provides throttle response which you prefer over Porsche defines ones. Enjoy! I suspect at some point in the future, manufacturers will add a custom throttle mapping feature to cars, perhaps Porsche custom drive mode will add a throttle map.
