I installed long tubes on my truck several moths ago the truck has been sitting for a good while during some training I have been doing. I need a inspection and I forgot the good state of NC requires obd2 so I am throwing codes due to my long tubes and no cats, is there a cheap easy fix for making them happy and read correct?

 

Get the PCM tuned to turn off the O2 codes

 

Any suggestions on a good tune? I want to add a electric fan to it as well and a wiring harness.
