SES Light - P2A04
I got my tune about 3 weeks ago and after about 200 miles I get this code: P2A04 O2 Sensor Circuit Range/Performance. I asked Nelson to delete my rear O2s when I ordered my tune. Any ideas on what this could be or maybe he just didn't delete the rear O2s?

I just took the cats off an 05 ECSB 5.3L and got the same P2A04 code. It is listed in this document towards the bottom of page 8. http://redhat3.admarkonline.com/~sup...install-46.pdf
It is O2 Sensor Circ Range/Perf Bank 2 Sensor 2. It is not one of the NORMAL codes turned off when you delete rear O2s. I have never seen this code in the 2 tuner packages I use to edit PCMs. I'm thinking it may be something new added to the 05s since that is the same year you had it pop up on.
