Increases in Flame speed does not necessarily increase power or efficiency.

For example:
The Lean Burn operation in Gen-1 Insight is actually a slower flame speed , but yields a higher energy efficiency... where the rich burn in the same engine has a faster flame speed , but a lower energy efficiency.

As both Niky and Tvago have pointed out, water injection and EGR change the chemical reactivity rates and surprisingly to some, they can be used to accelerate and stabilize certain flame situations when all logic tells us they would quench the flame.
