o2 Simulators
 

Where is a good place, cheap preferably, to purchase o2 simulators for a 2005 GMC Sierra 1500 5.3L V8?

Can't you get someone to tune your truck with there lap top and get them to fool the computer that it has them on? I say this because my brother is in to tuning like on his G8 and he did that on that car. Save money and get your truck customed tuned at the same time well that's if they know what there doing.

Just go to a web site and you can find them for bout 20 bucks a piece. A custom tune can delete the rear O2 sensors. Thats what I did on mine.

ok, name some websites because I seem to be having trouble locating any?

Here ya go friend.
