Correct. No boost is created at idle. In fact, you don't wan't boost to be created...why subject the engine to a high load when it doesn't need to be? The reason boost isn't created is due to the bypass valve that comes with the kit. The valve reroutes most of the air from the supercharger back into the supercharger itself, instead of the cylinders, effectively preventing any positive pressure from occuring there.
Boost is modified by changing the pulleys, as they determine the effective rotation of the supercharger's rotors. If you wish to 'turn off' boost, you would need to remove the short belt connecting the supercharger pulley to the driveshaft pulley. By doing so, everything else in the engine (power steering, alternator, a/c) continues rotating as normal, but the supecharger does not. So the air just passes right through the lobes and does not get 'crammed' in.
