The Sprintbooster actually works similar to a voltage regulator. The travel range on your pedal from no-gas to pedal-mashed had corresponding voltage. When you perform a throttle reset the voltage is fairly linear from 0V to 5V. As you drive the car on the highway and in other similar sustained MPH scenarios the computer/throttle body learn and instead of a linear 0-5V through your pedal travel it may be changed to 0-1V for the first 50% of travel and 1-5V for the last 50% of your pedal-mashing. This causes less acceleration with the same amount of pedal push as was during throttle reset.

The SprintBooster re-assigns this voltage. Now when the throttle is reset again with the SprintBooster installed you will see a voltage range from 2.5-5V (obviously it is still 0V when you are not on the pedal at all). What this does is create less pedal travel necessary to achieve the same throttle response as you would previously see by depressing the throttle significantly more (theoretically 2.5V = 50% pedal w/o the SprintBooster).

While this does not add ANY horsepower, it does provide better response of the horsepower you do have to the pedal, making the car a bit more peepy and responsive.

My $.02. Hope that helps.
