Thx for the info on the rear o2's man. I think I will just unplug em to check. Have not heard back from Allen.
I dont think Allen turns them off unless you ask him to. I think he keeps them activated if you are running the stock y-pipe with cats.
But even so, a CEL for no rear O2's isn't a big deal. It might run a tad bit rich, but it will run just fine...

I have to say it has been a while since I have been on this board, due to my previous legal issues.. It is nice to see all the new members and technical talent, thanks all!

Allright folks I have to take the family to go so Mickey Mouse, the upside is I will end up not getting any sh*t from the wife about the headers and ory! Hopefully I can order them while in fl and have them at my door when I get back, it will be a welcome site after 8 days of mickey and cinderella...
Bryan---you are DEFINITELY going to need some truck mod time after being in Disneyland for 8 days... Get that stuff ordered so you can have some good quality time in the garage!
Cool, so Longtubes in ory pipe in and new pcm in with rear o2's deleated. Truck has def woke up.. I have big time traction problems from a dig on cement and even worse on pavement. I installed a fuel pressure guage and it reads right around 60 psi all the way to redline.. I have to say the headers really uncaped some hp I was loosing. Problem now is the slugish 1-2 shift which I am getting looked at Friday at Circle D. One I have the shifts firmed up I will get back to the track and post some #'s. Thanks all.
900 mv for the 02's is about right; although with a narrowband they're really not too accurate at anything other than stoich. Most of the guys tuning with narrowband try to get the 02's to read 900 mv (I think its technically the right a/f).
