Help me understand timing

[Jason1320]

Thanks, that was very informative. There is still one question left unanswered. How does this affect performance from a tinker's point of view. For instance, on a basicly stock GT with my few mods, could I see a gain from advancing the timing and running better gas? Would it be in best intrest to lose the Jet Chip (cuz it sucks anyway) and go with a Steeda T/A kit? Or would a programable chip and dyno tune be the way to go?

Thanks,
Jason
