Hi,

Yes, 5 degrees after TDC is what they did. I believe it was a mis-guided
attempt at emission control. If I remember correctly it ended up increasing
some other noxious fume so they quit doing it.

Some of us adjust to 5 degrees before TDC.

There is a risk of pre-ignition doing this, which can cause serious engine
damage.
