im pretty sure its a cat prob, your tuner should be able to cut off the o2 sensors for the cat or a custom tune will do it, or a diablosport predator i know will disable them

Look in the book that came with your tuner. It lists all the trouble codes. The exact code means:
Catalyst System Efficiency Below Threshold (Bank 1)
So, yes, cat problem
Catalyst System Efficiency Below Threshold (Bank 1)
So, yes, cat problem
