Not completely accurate. The SB does not speed up the opening of the TB. What it does is open the throttle more per prescribed input, e.g. takes throttle input and opens the butterfly at a rate of stock x 1.3. You are now getting more throttle vs. the amount of input making throttle input seem faster.
