You are incredibly wrong about that. Buy one. And then see if you think the same thing. And, you cannot just push the pedal down faster. That statement tells me people have no idea how a drive by wire vehicle operates. It's not one to one metal linkage like a race car. Your TBI's are programmed to have a max opening rate no matter if you drop a bowling ball down on the pedal. The SB changes the resistance allowing the TBI's to open at a much faster rate. They work even better when you have a full exhaust and good intake system but those are not necessary. They do not add horsepower and they do not add top end miles per hour. However if you want to be quicker in the quarter mile, spend the money and return it if you don't see the difference.
