Hi guys, it's been a while but i've been out of the country for the last 3 months and my truck has just been sitting.


I'm getting o2 check codes for the rear o2 sensor. I'm told this is due to the headers and high flow cats in combination with the SC. The engine is flowing to much air for the senors to read properly. That check engine light is really annoying and i want to fix it permanently.


Any suggestions?


I know you can bypass the rear sensor with a plug in simm (JEGS has em). Any issues with this method? Are there replacement sensors available? If so where do we get em?

I was getting some O2 errors before I updated my Radix tune with the latest from Magnacharger, have you checked with them to see if you are up to date?
