Default too lean or to rich???

I have a 08 kfx 450r lexx slip on, hmf optimizer, and fci intake. when i'm at full throttle it seems to stutter a little and if i let off my throttle it backfires pretty bad and if i'm ridding at night i an see a 6 inch blue flme shootin outta my pipe. i'm not a hundred percent sure but i think i have my controller set on 4.5/5/6, am i running to rich or to lean??? and also i'm ussin 93 octane. any advice would be appreciated, thanks a lot,

Jared

try 3.5 / 6 / 5 on your controller and see if it better or worst
