Tune a bit for 1/4mi ?

[Garry]

If I luck out, I might finally get my car registered before the weekend and my take it to a track/airport to get a couple of quartermile runs in. I will be doing some blackbox logging, but as the car is stock, and the WBO2 isn't here yet, how much good will it do? Can I do anything worth the effort (read: .1/.2+ improvement) as it is right now?

Without a WBO2, you could try to get your WOT NBO2 voltages into the range 930-950mV; not as accurate as a WBO2, but better than nothing.
