Second video is better, actually tries to to show something to back up what he says.... Some folks more knowledgeable than me, who have analyzed it actions, are not in favor of it ...
With physical throttle systems, the throttle body moved as much and as quickly as your foot moved (good ol' days).
With electronic throttle systems, the right pedal makes a request, the pcm interprets that request, and then mitigates it before commanding the throttle motor to open.
The pcm considers any number of criteria as excuse(s) to open / close the throttle more slowly than the driver's foot.
(Rarely, it can open the throttle even less than the driver asks, effecting a softer top speed limiter.)
EXAMPLE: Your foot moves from 0% to 20% throttle in under 0.25sec.The ONLY improvement in results for 0-60 and 1/4 mile runs would be the reduction / elimination of the lag.
This is because it reduces the time it takes for the gas pedal to send a request to open the throttle body to the EUC (in my estimation, without the mod, about 1.5 seconds). HP and everything else doesn't change.
This mod makes the vehicle absolutely LEAP of the line, and opens the throttle body faster (for example, depending on your setting, gas pedal at 1/4 with the mod is the same as gas pedal at 1/2 without)
It always takes OVER 0.25 sec (much slower in an SUV vs a wee lil bit slower in a 'vette) to open 20% wide.
The pedal 'commander' exaggerates (lies) about how far your foot moves (this is not an opinion).
Your foot asks for 20%, the pedal 'commander' asks for over 20% (cleverly moving the throttle more quickly as well).
How much more (and thus more quickly), depends on the degree to which the pedal commander is told to exaggerate.
To get a bit more complex:
Say your foot goes from 0% throttle to 100% Wide Open in 0.25sec.
To be precise, 12.5% in 0.03125sec, 25% in 0.0625sec, 50% in 0.125sec, you get the idea.
Pedal 'commander' exaggerates how far your foot moves, which effectively also exaggerates how quickly your foot moves.
Although 100% throttle cannot be exaggerated (101% throttle?), the rate of travel is effectively exaggerated by exaggerating at each step along the way to 100% Wide Open.
TL DR:
The pedal 'commander' is more accurately referred to as a pedal 'exaggerater' than a pedal 'quickener'.
The quickening is being achieved by the exaggeration.
