Some engine mods can be really expensive, but nowadays with the widespread of electronic fuel injection it can be easily tuned to improve the efficiency. Altough some other mods such as a different profile for the camshafts would be desirable to optimize the results of an electronic tuning, it would already lead to a significative improvement on fuel-efficiency...
