Tried timing retard, timing advance. Large and small amounts on both sides.
DIfferent fueling settings (RICH, LEAN IN BETWEEN)
The best setting was stock timing map down low with 12.5 a/f ratio.
But remember I stall at 1600rpm and under 8 psi of boost 2700rpm within 3.5 seconds, that is very low and it acts different than the other motor that stall easily to 3600rpm + under boost in 2 seconds
