You should get the tuning kit that is around $35 at summit I think. My eddy runs great so don't worry about what everyone else is saying in here lol. I will check my tuning manual here later after I get back from work and let you know more.

Out of the box a 600 runs rich on a 306 with stock heads. I had to make mine 2 stages lean to get it to burn right.
