IMO get with PMS and they will tell you to install 08 head with 08 flash.
I have 09 dragon 800 with Fix kit, 13.2-1 head, slp pipe can, PC5. I tried to tune the 2010 flashs and could not get it run good. I had my dealer load a 08 flash and cleared the PC5 map and it runs great. I'm still going to tweek on the PC5 map at idle and 7000-8250 RPM. So the PC5 gives you the tools to fine tune.
