N/T set-up

I just would like some verification about a couple of concerns I have regarding n/t parameters I am looking for.

When doing WOT runs, where would the optimal targeted o2 voltage be? I always heard around .92-.94 is ideal where anything under .9 would be too lean.

Also, how low should the timing drop to achieve the best performance numbers. I did a few runs and it seemed to be all over the place, usually in the low 30's with a few drops down to 27. Before I did the latest mods and did a few runs (over a year ago) I thought I remembered it being consistantly in the 20's, even as low as 23. I am currently under the process of tuning, unsuccessfully I might add, so any suggestions would be appreciated. I also have larger cams with adjustable cam gears which are causing me problems as well since I don't have them dialed in perfectly yet either. Most of this needs to be done at a dyno and with that, remap the fuel and timing curves to adjust to my new set-up. But I am just trying to do as much as I can out of my garage for now. Thanks for the help.

I can't remember exactly the number, but I think it's 24*

Once you go wot it should stay the same. The computer locks it in there. Log the throttle % and see if it moves since you're having problems.

Don't try to adjust your fuel by the O2 #, the sensor is very imprecise and you could detonate. If you must, try not to let it go under.95v until you get it dynoed. It may be safe to run at .85v but do you want to find out unexpectedly that it's not? EVERY CAR IS DIFFERENT. The same for the sensors.

I'm sure you can find some tips on the cam timing if you search. I don't have any except the obvious ones.
