You can buy the PCV for your 03. I recently was given the info from another member and so I called Power Commander and you can use it. I have one installed on mine and it seems to be working great so far. They are selling them in the rider discount area for $256. All you have to do is follow the directions on the disk when you get it and down load the PCIII map from the disk. www.powercomander.com also has maps on there site.
