High Altitude Emissions Tracking?

[mrhemi]

Just aquired a "new to me" 2004 Dodge Ram 2500 4x4, 5.7, MT, SLT. I noticed an the build sheet is states "High Altitude Emissions Tracking" My concern is, since this vehicle was sold new and spent it's entire life to date in the Salt Lake City area, does this indicate it has a high altitude fuel curve in it? Since I will not be operating the vehicle at 600" asl and below, should I be concerned with the fuel curve?

Thanks in advance.
