Here's the EFI programmer for the 2010 YZF450 This means that Honda, Kawasaki and Yamaha all have a way that you can reprogram the EFI, but Suzuki ?? ~ nada. I have heard that the Honda and Kawasaki programming software is "not exactly" user friendly, and that's why Dyno Jet sells so many PCV's. But seriously, where's the Factory Suzuki programming tool?
