O2 Sensor Code

[Cody Shupe]

I have a 2013 1500 Laramie and I keep getting a P2098 code. I have replaced all 4 O2 sensors today just for a start and the code has come back. I have JBA long tube headers and I never had any issues until these were installed. Anybody have any ideas on what the issue may be? I've been seeing things about possibly the PCM being messed up but I dont like that idea.

You need a tune to disable the rear O2 sensors. As far as I'm aware JBA doesn't have catted mid pipes for the Ram and even if they did most highflows will still set off a catalyst efficiency code. I would also suggest rear O2 simulators, but honestly LT's really need a proper tune in just about any application to actually provide any gains and in some cases for the vehicle to run correctly.
