Any sugestions on timing for engine when not in boost, on low compression motors. Currently tuning LS3 forged bottom end 9.5:1CR stock ls3 heads.
Is it common to increase timing to compensate for the loss in cylinder pressure due to CR? The off boost HP/TQ numbers look low on this car.

More advance doesnt always make more power. The only way to know for sure is to put it on a dyno and see what the motor likes.

I did not want to spark hook check every llad range as this would be very time consuming.
Just was interested in what the common tred was.
