My question about these devices is what they actually do. Do they simply 'magnify' pedal inputs?
For a very hypothetical example: I press the pedal down 15%, now the throttle plate opens 30% instead of 15% for a larger response. Car goes faster for any given accelerator input.
*or*
Do they increase responsiveness by removing the delay that is typical of drive-by-wire systems - for example, I press the pedal down 15% and the throttle plate still opens to 15%, but now it does it in 0.25s instead of 1s, and the delay between pushing the pedal and moving the throttle plate is reduced? This would make it feel more like an old car with a mechanical throttle cable.
I feel like it's the first one. Which would "feel" like the car is more responsive....if you don't also have cars with a mechanical throttle cable to compare them to. But I'd be much more interested if it were the second. I have a few other older cars, and they just feel so much more responsive (even with fractions of the HP).
