I did a search for all your posts Mike,you have had so much trouble and done so much with this vehicle that basically it is impossible to diagnose. An accurate diagnosis depends on having what is called a baseline, that is, to know what state a vehicle is in or was in prior to a drivability problem occuring.
Performance depends on the whole system working together correctly, too much has been done to this engine.
This may seem blunt, but I see similiar scenarios everyday.
Oh yeah, just my opinion, and opinions are like anus's, everybodies got one.
