O2 Sensor questions
I just installed LG LT PRO'S with cats. LG says to blank off the downstream sensors and only use the upstream location for (move the downstream O2's forward).
Is there a downfall or advantage to using both sets (upstream and downstream)? If you were to use both, and utilized the downstream O2sensors in both locations (upstream and downstream) would there be any issues? I have 4 downstream O2 sensors and would use them if it was advantage.

It depends on the emissions in your state, I think some states will require you to run with the rear sensors. In that case you will need an extender to allow you to reach the rears. I assume you have the new converter connectors to allow you to use the rears in the front? The converters you can get from LG, and maybe the extenders as well.
The rear O2s measure the efficiency of the cats. If you have no cats then they are a waste of time. With high flow cats I would wonder if they would pass some states efficiency tests...
The rear O2 error codes are usually removed when doing a tune, if you have already done this then re-installing the rear O2s may not get you anything.
