For those considering or even owning a Sprint Booster it may help to understand just what they do.
All, and I mean "every" modern fuel injected car now uses an electrically-controlled accelerator pedal. Years ago, there was a cable or rods from the accelerator pedal to the carburetor or fuel injector throttle body. The accelerator action was entirely "lineal" , meaning that pressing the pedal half way opened the throttle body half way, etc.
Modern cars have a pure electrical connection, which allows mfgs to moderate the throttle openings. They all do this in the lower gears, presumably to protect drivelines during the warranty period. So, a "full stomp" from a standing start will not open the throttle all the way at first. The accelerator pedal sends a delay signal.
What the Sprint Booster does is to change the signal from the accelerator pedal so as to pop the throttle plate "full open" with your "full stomp."
I have used Sprint Booster on since 2005 or so, always with great results and joy.
Sprint Booster is EZ/PZ to install with one caveat - undoing the electrical connection at the Panamera's accelerator pedal is a challenge and a nuisance.

 

I believe 1 screw holds pedal in place. Rem9ve screw. Plug connectors into harness, put pedal back and screw down. 15 min job total, plus couple hours having fun dialing in the sprint booster settings.
