I was wondering what O2 voltage everyone shoots for at WOT. I know the stock sensor is not great and WB is much better etc. Just wondering what people do.

Using the regular non-wideband sensors, 890mV is my usual target but it's not a precise measurement. It'll get you in the ballpark.

Good question. What if you can only get one to 890, and the other reads 910?

If one reads diff from the other then you may have some kind of exhaust leak or somehow more air is getting to one of the other sensors. SHould be ok as long as they are not too far apart in value...

To be safe I would say aim for low 900's. If you see 800's then it is ok as long as you dont have a power adder like nitrous or boost but make sure it is high 800's. Not the best way to tune tho...if ur serious get a wideband LM1 you wont be sorry

Would the leak have to be forward of the O2? I have been clamping all over the darn exhaust system and can't find a leak. I am using Hooker shorties and a stock Y...

It will only effet the o2 if the leak is ahead of it. If you take it to the dyno and they put a tailpipe sniffer in the exhaust and you have leaks this to will throw off the readings

So they really should be that close, even with the flow differences on each side of the exhaust?

Could I have slightly damaged one side when I put my headers in? That side was a pain. There is like no clearance right there because of where they put the bung on the headers. Barely enough to get the O2 sensor in.
