No, what I mean is what is the spark advance in your Port Throttle Closed SA table, above 5000 rpm, 100KPA? I suspect it is around 20d. When the secondaries shut off, the ECM switched to that SA table.

What have you done with the secondary vacuum sensor? If I remember, you have removed the port throttles. Any other mechanical modifications to the port throttle system?
