So you have not actually make a full pull under boost and WOT on the dyno yet.
You have only tested it on partial load , on the primaries, correct.?
The 78's sound good on the sec side as a start but it may want fatter than 65's pri @WOT.
Yup the crank sensor signal matters. The air gap setting is critical.
may have seemed rich because of misfire under load, cause of the crank sensor trouble.
65's primary just seem lean for this one.
