CAMARO6 - View Single Post - Installing primary cat deletes without a tune

My main question is this. I have heard that you could take the primary O2's and put them behind the secondary cats and avoid check engine lights. Is there any truth to this.

I am not ready to tune the car just yet. I want to do flex fuel first before spending money on tune.
