Runs worse as it learns....

well you did kinda patch it up by dropping 8 degrees at the distributor. perhaps in that case dropping 8 degrees across the map, putting it back to normal at the distributor, then slowly bringing it back up would be a good starting point...

but without a knock sensor, kinda hard to do any decent knock logging; so perhaps you should consider installing one?

If he is running the 7747 without a knock sensor and has not turned off the forced knock test there is a good chance its the test itself not the spark map causing the knock.
