I will be adding headers to my ZL1. I have HP tuners. From doing some research it appears I need to turn off codes: P0420, P0430, P015B & P015D.

At there any other codes I need to turn off?

Also, do I need to make any adjustments to O2 proportional or integrator tables since the primary O2 sensors will move further away from the engine?

thanks
