Actually, the S2000's aerodynamics are bad enough that the gearing is probably not the biggest problem (lol).

Newer engines have shown how effective EGR is at increasing part load fuel efficiency. The S2000...has none. It has no cam phasing either. The low load efficiency as a result is BAD.

@OP congrats on the Cruze, you can tune the ECU to improve efficiency under boost at the expense of momentarily higher EGT (probably not a problem since you're not racing the car).
