You won't have to do much at all with the Sniper. We run 2 of them, mainly because of the mountains and elevation changes, and they handle the changes quite well.

As long as you still have compensation limits up around the 10% range it will adjust the fuel as needed. If you need more compensation than that to deal with the mountains then the base fuel table probably needs more work.

I just turn the learn percentage down because I don't want it to corrupt the learn table when I'm dealing with elevation swings.

You can even have a different tune at the ready with the compensation and learn where you want and quickly load that in before you tackle the mountain, and let the Sniper adjust to those elevations and then save that tune to use when needed. Only takes a few seconds to load one. I've done that before too and then compared notes of the differences.

This kind of stuff is one of the biggest reasons to have this EFI
