There are plenty of posts on the site about the "deristrictors" TRE's. It is a resistor that tricks the bike into thinking that it is in 5th gear all of the time. From what I have read yes they do work on the 2000-2001, supposedly they do not work on the 02's because the bike is restircted in 5th also. But I have read a couple of posts that it did work on the 02's but they used the EMS box. They people that used the PCIII said that theres did not work.
