I will. I'll put it in Open loop and take a ride. I have two wide band setups. Left and right banks with two gauges in the truck along with a fuel pressure gauge. I'm going to sit tight until I have the second one hooked up on the right side. The right one went bad before all this and I have another one coming. That will help. The only thing I don't like is the o2 bungs are after the cats on this header y pipe setup. I have 200 miles on this motor and with the cat looking looking like it does, I'm going to sit still until I have everything I need to figure this out.

The pcm is suspect. But if it's reading on my laptop threw HP Tuner I would think it's working correctly under the hood. But anything is possible.

Everyone - Thanks for the in put and I'll post my findings.
