Can a gryphon programmer shut off my o2 sensors? Or is there some other way to make them think they are working properly but not be on the truck? I have been calling around to get a "y" pipe made for my truck because I am going to be using pacesetter long tube headers and the price I am getting are retarded. I found that pacesetter makes a "y" pipe for my truck but u can't use an o2 sensor on it. Any ideas?

 

The o2 sensors are needed in the obdII systems.
You are going to have to try and get them installed.
JMHO
This is probably the best way for the rear o2's only:

How do you mean need them? The only emissions testing that we have where I live is a gas cap test. Are you talking how the truck will run? What if I just welded bungs onto the Y pipe and did the gotts mod to all 4 of my o2 sensors?

 

You need them for your pcm to operate your motor correctly.
If you totally abandone all your o2 sensors the motor may run rich=poor mpgs and you will have cel light on.
You can only do the gotts mod to the rear o2's.
Yes get your Y pipe and have bungs welded on it.
You should contact a tuner directly if they can shut off your o2's.
