Ive tried it with/without dfco enable/disable, open/closed loop(worse with close loop), maf disabled,
Tried the same with the coast down timing, idle timing, main timing,
All I can think of is airflow adjustment somewhere must have a timing correction factor coming into play when coasting/part throttle and cam is either above or below that threshold.
