the sensor is supposed to take in to account temp & elevation...
you should be fine.

... but it is not going to be right on from what I have gathered in reading tuners notations on here.

I just don't think the air temp and air pressure sensors are that sensitive.... or maybe the ECU doesn't have a lot of adjustment range on the base map.

The map you are loading will be lean for your elevation... based on carb logic.

Question is, is the ECU adjustability range that great?

You'll just have to try it and find out.

Since the PC map is a piggyback +/- on top of the ECU metering, if the range is that great you will be real close.

Theoretically it should be close, but in practice the A/F ratio seems to not translate perfectly between large elevation changes (A guy here ran a map in Colorado that was made in California a while back, and apparently it didn't work out so well)
