So the last couple weeks I have been getting an error code on my mustang . P0430 is the code which is "Catalyst System Below Treshold (Bank2). I have researched it and bank 2 means the 02 after the cats are reading something is wrong. The problem is since I have been running the prochamber it has no cats so the 02's after it have been turned off by the tune I got.

Anybody ever run into this error with the bank 2 sensors turned off?

I have reflashed it and it comes back after 3 rides.
