I'm guessing there would be some minimal loss. I've heard for NA it's about a 3% loss for every 1000 feet in elevation and for a turbo it's more like 1% for every 1000 ft. Maybe someone else can confirm what the actual loss would be on the N55. I'm in Colorado Springs around 6000ft so I've been wondering this myself.
