P0430 Code after reverting tune to stock?
Hi all!
I recently bought a 2012 Camaro SS that came with a spectre CAI and a vararam power wedge installed. The guy that had it before me had it tuned and it was burpling all over the place and felt like the idle and drive rpm’s were cranked up to the point it lunged a bit coming off the brake. I reverted everything to stock last night and drove around for a solid 45 minutes. Right before heading home the check engine line popped on throwing a P0430 “catalyst system efficiency below threshold bank 2” code. After a little research it appears it could be the cat on the passenger side or the o2 sensor. The question I have is, will it throw this code if it’s not tuned properly? I never had it throw the code driving it recently, albeit I never drove it for as long as I did last night. Sorry for the long post, but curious on the thoughts to address. I was planning to go with long tubes this summer at some point anyways.

A CAI should not cause this code, there is a chance that the other tune was rich and screwed up the cats, You can hook a scanner up and watch the O2 sensors and see if they are working correctly. If you are not able to then I would try to replace the 02 sensors ( all 4 ). If you are going to LTH soon with either no cats or Hi Flo cats ( I recommend the cats I think it sounds better ) then this code should be taken care of as the rear sensors will be de tuned or shut off. I would still run New )2 with the headers as the fronts are still important.

Wondering since you are saying you are straight piped do you still have cats and is there still downstream o2s. Its possible the previous tune had the downstream o2s disabled. If you do have cats and the previous owner had a verbal tune installed your cats are probably melted.

If you are not sure how to do it, watch a you tube video. If it was really rich I'd assume cats are probably shot. Not a big deal if replacing them anyway.
