What mic06 said is spot on. There is an actual lag built into the system which the SB removes. In addition it makes the throttle more sensitive. If you like that they are worth it. I love them on petrol manual cars.

If they're pointless then the sport button on the e46 m3 is worthless as its basically the same thing, and BMW built that in themselves.
