As for the rear O2's, I would just leave them alone, no anti-fouler's.

Then all you would need is a "no cat" program designed to ignore the rear sensors to eliminate and P0420 codes, and a "cat" program that will watch the sensors.

Should be no sweat for Bill to handle.

That is what I was hoping for. So it is doable to "turn off" the rear O2 sensors? Was not sure how that worked on the OBD2 systems. That would be amazing! The power...the sound

Regardless of what tuner you go with can you let us know how everything works out?

I am going with PHP. I have gotten to much help off of these forums to go with some one else. Also, I am just feelin the family owned and operated business thing. Usually they give you the better service and take the time to make sure things are done properly.

But for sure I will keep you updated. I will post some videos as soon as I get it done.

The family business feeling kinda grows on you doesn't it? It's like a disease that you WANT to spread.

It'll sound goooood.

Ok, I just ordered the dual 3" exhaust cut outs. I got them with out the remote openers for now just to make sure every thing works as planned. If I like them and all goes correctly I will get remote openers so when I turn off the truck to set it to the "offroad" tune I can open the cut outs at the same time with out leaving the privacy of my own truck
