I have often wondered how compression is accounted for while tuning and have decided to ask for others opinions. I am not sure where compression is taken into consideration while tuning. Cylinder volume is taken into consideration for in {B0104} but i cant seem to grasp the ideas for compresion. Does cylinder volume need to be adjusted when you add a 3cc piston or a -6 cc dished piston? Ideally you are changing cylinder volume right? What about shaving your heads to add compression this too is changing your volumes but there isn't a place to insert the volume for you combustion chamber?
Thanks,
