My interpretation is that the time scales are matched on the graphs. I do think that there is no elimination of delay, or power gain, but simply a more aggressive throttle response.

It was a novelty, and I rarely used it. I found that it was easier to match revs with it off.

I only think it is a ripoff to the extent that SB create confusion around what it does, and leave the impression that it changes the power. Some purchasers perpetuate that. If an altered throttle pedal makes the vehicle better for any individual owner, then that is great, it is just a question of what that is worth to the individual.
