EDIT: A good video on Decel cutoff, and correcting popping and stalling etc
Sorry to hear you are still having interference. I have only shield my wires so far, I never had any issues with that as far as I can tell. I did buy the stainless wire, and ground the unit well. I did see numbers moving at and heard/hear clicking KOEO though.
Some updates, I found my damper had slipped. This meant when I pulled and locked the distributor and re-installed it timing was off based on the slipped mark. I also relashed my valves. Adjusting the timing raised vaacuum at idle and altered the IAC reading/fuel trim. I re-adjusted the IAC (TPS at zero) to regain a reading of 3-10.
Then I found that even though I had saved my engine as a 340 cubic inch and selected the #3 cam (twice since it didnt take the first time) the fitech showed it as the base setting 400ci with a #2 cam.
