You don't have to do anything with the secondary 'flies but removing or fixing them in the open position makes for more immediate throttle response.
This can have drawbacks, though (eg, too much throttle at lower rpm/higher gearing can make the motor bog down) and usually works best with the addition of a PCIII/V unit and revised fuel mapping.
However, if you remove/disable the secondaries on a post-06 Gen II, the fuel cutoff-induced 'snatch' becomes an issue again, thus requiring the FCE to cure it.
So, a proper case of cause and effect.
