I just put in an Intense PCM and threw a cat code. Figured it was bound to happen to me. I was going to replace the cat with a high flow and put in a 3" downpipe so I went ahead and had that done already. Now I am going to change the plugs. What plugs should I go with and how can I fix the excess fuel going into the cat? Can this be tuned down or is it something I have to live with because of the PCM upgrade code? Need to get this fixed asap cause I am due for emissions.

Basically what plugs and gapped at what should I get?

Your cat code may just be a bad rear 02 sensor. You may want to replace it, or get an 02 sim.
