You can not tune fuel with a NB. It can only tell you if you're off stoich (rich or lean), but can't tell you how much. IE usually making peak power at a 12:1 AFR (or 0.8 Lambda). Consequently the timing is more sensitive to what type of gas you're using. If you're using regular (as stated by the Owners manual) stock firing is fine--can verify by strapping it to a dyno and going from there. If you want to adjust timing, you'll need to put it on a dyno (don't go by feel), and slowly adjust it from there. Depending on your spark energy you should see some decent gains (don't forget to go to a higher octane rating when you adjust it).

I understand all that. but, Being as i have a Large Street Ported Motor, Factory timing isn't correct anymore right?

Eh, it's not going to hurt anything. (I'm currently on a large street port)
