    Just curious, did the EFI manufacturer recommend the #8 supply and #6 return. This shouldnt have any bearing to your problem, but those lines seem like overkill for a 347. 

    You have a lot of variables all at once to figure out, which is a big task. Hopefully it is something simple, like making sure the throttle position sensor is calibrated correctly. Big problem is going to be sorting out what factors are the problem and what factors are caused by other things sending wrong information. Testing, time, notes and studying, and probably a good few number of phone calls to tech lines.

    How do I make sure the TPS is set correctly?

    Does anyone know if the connector I posted is something I can even hook a laptop up to?  What does the type of O2 sensor do to effect the system?  I am going to try to check cam phasing with the distributor.  Any other ideas?

    I can't answer that question, but if I were you, I'd start testing the various sensors - MAF, TPS, etc.  If they're like ones I've worked on, they are supposed to have a range voltages they output in response to a known reference voltage input.  I would expect the information you received w/ your system covers that.
