Let's talk about tuning before LS1 Edit gets here!
 

What effect does a rich/lean fuel condition have on timing? What would be considered the best fuel #(o2 readings) for maximum power? How can changing injector pulse width effect power? I know alot of people have a basic understanding of this but I would like to have an indepth knowledge before I go trying to experiment around and flub something up.

Doug,
I can't talk on the pulse width for the injectors. But there have been a couple threads in the last few days that might be able to help you.
For 02's .89-.90 seems to be the best for every one. I have noticed my car flux from .87-.93 depanding on conditions. I have found at .89 I get my best timing.

Yes, it seems that .890 is perfect for O2s...

You really can't tune off your stock O2's. For an example of why please reference:
