I want to flash mine, but it's also a track only bike that I'm trying to squeeze every ounce out of without engine work. For a street bike with the occasional track day, I wouldn't. Spend the money on a track day instead. It'll be a lot better invested. Hell, before I started racing (but after it was a dedicated track bike, but just track days), I wouldn't do it.
