Effects of an Elevation Change?
Tuners, will moving from near sea level to 1600 feet affect performance? I ask because it seems to have made a difference. And not for the better! Thanks.

Everything else equal yes, but I don't know that 1600' would make a big difference. But I'm not a tuner anyway.

The first time you turn on your key following an atmospheric air pressure change, the MAP will read the base kPa and the ECM should adjust automatically.

Still slightly less pressure/oxygen to burn. Looking online, seems like about 3% per 1000 ft as an estimate.
