These guys are really helpful. If you call and talk to them in person they will set up the kit and modify the recommendations just for your set up. It will be spot on usually.
I called them on my 530 and they adjusted a couple of settings based on my favorite riding spots and it was incredible. I ride from sea level to 10k feet and never re-jetted. Just a fine adjustment of the fuel screw and tear it up.
No affiliation at all, just great success with it.
