I noticed 3 master switches in my 2010 dodge ram tune for disabling the downstream (rear) o2 sensors.

I set them to disabled as the cats have been removed and I disabled any cat and sensor 2 o2 sensor codes.

However now my fueling when in power enrichment, is very rich no matter what I command in the 5200+ rpm range, but maintains what I command below that.
Yes the cat overtemp thresholds have been maxed out to not play a part.

Should I re-enable the downstream o2 sensors via the master switches but leave the codes disabled?
