Installed Longtube headers and Offroad Y-pipe (no cats)

[whitesilvy04]

I went to my OB-2 02 sensor section to delete the back two 02 senors where my old cats were but i saw a list of about 5 different p-coded ones...

Do i need to turn all of them off? or is there a certain one i need to turn off

What about my egr? and Air?

i have a 2004 silverado 4.8L with your diablo

Thanks...

Yes, set them all to off.
If you have not removed the EGR and AIR systems, you do not need to alter those settings.

Thanks
