Yes Frank I will be there, that would be awesome. Thanks alot. And yes I wonder if the problem is my grounding. I have a large cable going from the battery negative to the engine block and that is where I ground everything so I have alot of stuff stacked there. Even the DFI ECU which is supposed to go to the battery but I figured it technically was.

Bobby,

Are you logging battery voltage? If so see where the battery voltage is durring the run when it is not reading correctly. I had an O2 sensor that would work intermittentaly and give me a flat 20 AFR reading on the run. The problem was my battery voltage was dropping to around 11.4 volts on the run. I replaced the battery and it worked fine after that. Also make sure the O2 sensor is turned on at least 30 seconds prior to recording your run. It has a heater element in it that must come up to temperature in order to work correctly. If you turn on everything prior to your burnout you should be ok. However if you are the type that turns on your system right before you stage, make sure the O2 heater is on prior to that.
