Maybe it's just me.. but a FI unit should compensate for this. Same with any airplane. You go up in altitude and lean the mixture.. but get the same performance than you do at lower alt.. actually better performance due to the cooler air.

less fuel being burned means less power being made, theres a reason the engines make a buttload of power have crappy gas mileage.

the only way to even it out would be w/ a turbo or supercharger and up the boost a little to be able to extract the same amount of oxygen as at lower altitudes.
