Plugged in my torque app. Saw sensor 1 reading .43 v and sensor 2 reading .03 v. Is that normal, a bad sensor, or a bad cat? No CELs either. Thank you

 

At idle? Completely normal. At WOT you should be looking for between .86-.87v or 860-875milivolts

Awesome. Thank you

 

You shouldnt even look at the voltage when WOT...not accurate.

 

Why even have an o2 sensor? Saying that you shouldnt tune with a narrowband is one thing, saying that they are inaccurate is another. o2 mv tuning on NA v8's is probably the single most common practice on LS1tech. lol

 

Can you do it? Probably but its still inaccurate.

Should you? Nope
