I drive it and enjoy it and without needing to mash the pedal to do so. I honestly don't think the throttle response is an issue but if others need a box then that's fine etto. 👍
Indeed
Waste of money if you don’t need one, a good investment if you feel the need.
I'm just interested in how it works, the subjective bit I can leave.
They’re basically an amplifier.
There’s a small box of electronics at the top of your accelerator pedal that has a chip in it.
I’d imagine (educated guess) that it was programmed exactly the same for every car in the range.
The PB intercepts the message from the accelerator pedal PCB to the ECU and adjusts the signal according to how you’ve set it, ranging from very little to ridiculously sensitive.
They work on basically the same principle as a tuning box.
