FOUND my problem and reason for ecm getting hot, bubbling my ignition module and all the weird readings on the ScanMaster and OTC. Internal problem in the negative battery cable. Passed ohm readings and continuity tests originally. Got it to stumble and act up in the garage. It was near where the passenger header is closest to it (3" away). Cable sheath is fine. Grabbed the cable while idling and it stumbled pretty bad. Repeated it to verify and yanked that puppy completely out. Cut it in pieces so I would never be tempted to use any part of it for any reason. Put in a monster 00 negative cable ($9.99), routed it a little further from header and secured to head. Every single symptom is gone. Car pulls very hard again and now I am ready to turn it up to 25psi and see what she does now. ME-R system back in with the 83#ers. Best the car has run so far was a 11.4@117 with 20 psi and there is more in it.
