    Argo EFI engines at high altitude.

    I know that a naturally aspirated engine losses approx 3% of its power for every 1000 feet above see level, so how much of this loss is prevented with the EFIs?

    I know the EFIs can automatically change the fuel/air ratio, but I am assuming there is still a loss of power at higher elevations. If so what kind of loss is there?

    I am interested if anyone has experience with a Frontier with the EFI vs a Conquest at altitude.

    Efi compared to carb doesn't make that much difference with elevation. Best thing for high elevations is a turbo. Air is thinner up there, so you don't get as much in a charge during intake stroke. A turbo forces it in, so you won't see as much of a power loss.
