Spark timing dropping at low cylinder airmass - 2013 ctsv
I have noticed that the spark timing drops from 12-13 to 5 then goes back up and it makes the car lunge forward slightly when the converter is locked.
When the converter is unlocked the rpms will drop and then rise back up.
I have tried to increase the min spark at those cylinder airmass levels as my tuner suggested, but it has not worked.
How can I fix this?

The spark drop happens on decel on the highway at around 70mph and it will stop once my speed decreases.
