That's not efficiency! That's specific power.
Due to the layout of a 2 stroke, the power stroke is cut short by the exhaust port opening, and you fart nearly half the energy out of the exhaust in a delicious-smelling haze. Effective at producing power, but not efficient.
Maybe if you ran some sort of thermal energy recovery on the exhaust side, you could get the efficiency up... Not sure how a turbo would work on a 2 stroke - that's beyond me.
