Default How can i fake out rear o2 sensors???

I am doing long tube headers on my 2001 silverado 4.8. I am not going to be running cats and everyone says i can do the trick with the spark plug non foulers. Also i have been told to do a custom tune, which i dont have all of the money for. So i guess what im wondering is what are the chances that the spark plug non fouler trick is going to work? Thanks kevin

I know they use to make o2 simulators for the 02 models and older. Jegs and summit had them.

You should have got a tune first then got headers! Anyways I have heard of people using those casper 02 simulators. Just do a quick search above and see.
Good luck!

IIRC Casper received a cease and desist letter from the EPA awhile back and they don't make the sims anymore....anyone else remember that or has the beer killed too many of my brain cells?

Google "o2 sensor non fouler " this will work 95% of the time.

The anti-foulers trick does work.

I found a website called o2 simulator that I have purchased from for around 40$ works well on my 98 blazer and going to get one for my 2000 suburban. http://www.o2simulator.com/
