This is a portion of the last .XDL I took (my first real "drive"). I am watching my O2 sensor swing from ~50mv to ~900mv as I drive. I expected to see it more like hovering between 900 and 1000 as it went back and forth over 950'ish (like it did in the first minute or so of this history). I have made VERY little adjusting to my VE tables at this point. The truck runs OK but not "Good". My timing tables are still pretty off, too.

So, does this look like a normal first drive on a stock BIN or does it look like I have a wiring/other problem(s) that I need to correct before I start changing my VE tables more? This is my first time tuning so this is part of my learning curve. feel free to blast me if this is covered somewhere else.
