Looks like you have a vacuum leak. Also move to cam selection 2
I was looking for a vacuum leak but did not find one. I still have the FiTech caps on the ports not being used, I will double check the gaskets under the Throttle body and intake to make sure they are sealed.
Will advice tomorrow, job interview today.
Thanks

I am not going to try and start the truck again until I install a Fuel Pressure Gauge and change the oil, filter and plugs...oil smells of gas and is thinner and slightly grey I believe its been so rich it has washed out around the rings...I will advise later this week.
Check your exhaust system also. Any leaks can send false readings to the O2. I assume you have your O2 sensor mounted about 10 inches past the collector and there is over 18in of exhaust passed the sensor.
FP gauge is highly recommended. Have you read the plugs?
My O2 is 4" past the header collector as per the instructions. I have long tube headers. Also, open exhaust right now since I cant drive the truck to the exhaust shop yet. going to pull plugs tonight and re-start everything tomorrow.
It is a waste of time to tune and adjust any further. You Must get exhaust on this vehicle.
That is not stated in the instructions...my Fast system or Accel DFI did not require exhaust.
