SMR 510 POWER COMMANDER?

While my 2008 smr 510 is getting some engine work done, I had a chat with a gentlemen in facebook about his 510 with a power commander. (He had it tuned with a custom map)
My bike has the arrow exhaust + full power-up kit, "race-mode" and all the stuff. Runs like a dream, no spitting flames () or backfiring. This person said his also didn't but was running lean on the dyno and PC + custom map gave smoothness and more mid-range power.

I can get my hands on a PC3 and a map for the bike from PC's website but does it need it?

i had to have one on my 2010 SMR due to running lean off idle would cause it to stall on decel. if your not having problems, perhaps you won’t need it but mine does run a good deal cooler w the remap. bottom line - well worth it to me.
