I own a 2007NNBS Silverado and I allready have a good exhaust guy to take off my cat(s). But I need to know what my options are for tricking the diagnostics system so I don't get a check engine light. I know my brother had O2 simulators for his 4th gen Camaro but I can't seem to find anything like that anywhere. So is there a programmer with this function? Or a way to loop the wiring? Any advice or any kind of info would be deeply appreciated. I thank you all in advance but I will deffonately be corresponding back and letting everyone know how this goes.

 

A custom tune should take care of that. We have several sponsers who can take care of you

 

A tune would do it like said or you can try PLUG DEFOULERS.. I ran them for over a year without a SES light, passed emissions..

 

Mangled03, what happened after a year did you ever get the SESLight? And I'm in Florida and we dint have emissions testing here. And if I do the defoulers I want to make sure I understand how that works. If I understand correctly it pretty much just moves the O2 sensor a few inches so it doesn't detect all the extra gases.

 

just get a tune

 

Correct, because i went with a new pcm tune.. Other wise i would have left them in.. I had a thread about it back in the day on here, alot of people didn't believe that it works.. If you dont want to dish out the money for a pcm, it is cheap, like 20 bucks and drill out to of the defoulers, you should be good to go..

 

get a tune, you can gain more power and get rid of the light.

 

I couldn't find your post. Do you have the link? Where did you get them? The ones around here are not long enough.

Sorry didn't read about having to drill 1/2 hole in them. I'll try again.

 

Tune em out

BTW, I searched and I can't find the thread with the plug defoulers either, I remember seeing it a long time ago though.
