Sure if you have unburnt fuel due to bad combustion you stand to have predetonation on the next firing cycle. This is a negative force trying to push piston down when momentum is moving the piston up.

This is one of the areas of attack I am doing on a stock build. Not looking for power but wanting fuel economy. Power will just be a bonus.
