Hi smokinvette. Doug here with a annoying problem with my 2002 Z, I recently put LT headers on my car, since then I keep getting code p0430 every time the car warms up and its idling?? I know this code has to do with emissions, but that check engine light just annoys the heck out of me! Will a tune take care of this or what can I do to get this resolved?

Your rear passenger Oxygen Sensor is out of range, You'll definitely get this code if your running Highflow CATs. It isn't affecting anything but as you said, it's annoying...

Yes a proper Tune will take care of it permanently!!!!!
