None. Current (and recent) production engines utilize the same PCM calibration.
2003-2005 XS models WERE different, however.

According to the service manual, the recommended WOT range was 5500-5800. Rev limiter at 5900.
Some calibrations vary.... so it would be wise to have the calibration information read from "one specific ECM/PCM" in this case.
