What do you think of o2 simulators? Just did headers and x pipe and car runs like you know what. I have a predator tuner and it doesen't help what do you think if i leave it alone and just add the sims?

02 Sims will not affect the way your car runs in any way, it will only prevent the deletion of the rear sims throwing a code.

I recommend you go to a wooded area, throw that predator tuner as far as you can into the woods, then go get ya a real tune from a tuner, i prefer EFI LIve

I have a sneaking suspicion that you don't like the predator! Hmmm...

Did you make sure to connect the 2 primary sensors to the appropriate sides? If you get left and right mixed, it will run right like a cold weedeater. The secondary sensors are just cat monitors.

I was at this point once, I swapped the old 02's for some 13111's and it fixed it. Hope that helps

13111 is the part number for the Z06 rear 02 sensors. They can be had at any parts store. I get mine at advance auto. They are supposed to have better heaters in them. They require changing the connector on the sensor but its worth it. My car ran bad until it was warmed up because the location of the 02 changed. The 13111 heats up quicker so it reads accurate from the start. I would think you could change the switchpoints in that fuel trim as well. It would take some tuning, I would run the car open loop and see if that clears up the problem. If so its an 02 issue.
