Looking for O2 simulators for my 2006 Silverado with the 5.3. About to remove cats and want the check engine light to stay off. Where can I find these?

 

Tune it.

 

Reason for removing them?

 

X2. I'm curious here too. Why would you set yourself up for the agrivation, smell and possible federal fines for nothing?

 

One plugged cat so Ima take them both off and just run a muffler. And where I live in south Louisiana we don't have emission testing so it won't bother me. And ok I have a bully dog on it right now but if I bring it to get tuned can I still use the bully dog on top of the tune or it won't work like that?

 

I have some sims on my 96 c1500 but I can't find any for these newer year Chevys. I'm guessing they hard to find

 

No you'll get more power and options from a real tune. But you can't have both. I went through this trading my Diablo Predator for a tune a shop.

 

Trash the bully junk. Flash it back to full stock knock the cats out and go find a custom tuner and get it dyno tuned the end result will be way nicer.

 

They don't have them because
1. The dont work on these models
2. you don't need them. Custom tuning software can turn them off.

As mentioned get a custom tune. It will take care of everything and you wont need the bully dog.
