Headers/High flow Cats/Codes/02 Sims???
DTC P0420 Catalyst System Low Efficiency Bank 1
DTC P0430 Catalyst System Low Efficiency Bank 2
These are the codes I'm getting every now and then. I've got Dynatech Headers with their High Flow Cats and Borla Stingers. Would someone please be able to tell me how to make my PCM quit throwing these??? Will 02 Sims cure the problem? Thanks in advance, cause these codes are triggering the check engine light and it "bugs" me. Thanks,
Loudsam

Hey Loudsam- I have the same set up as you, and I have the same codes.. O2 sims will fix the codes, or you can get an LS1 edit/Dyno tune and just turn the O2's off all together...depending on how the emissions are checked in your state (if they are checked) will determine how you might want to handle this.
if you have a sniffer test in your state, then you will fail emissions with 02 sims.. the only way might be with a dyno tune to adjust...but if they do an OBDII test where the just plug into the computer and check for codes, the LS1 edit or 02 sims will work.
