Watch your Boost, Feedback Knock, Fine Knock Learn, and DAM, essentially. There are plenty of other factors.

If you're dead set on Etuning, Contact Eric @ Torqued Performance, Bren Tuning, or if you want the best of the best, JR from JR Tuned also does E-Tunes.

 

What should I be looking for in the boost? What is the max boost the car can reach safely (conservatively)? Should I look for sudden boost drops? How about the feedback knock, fine knock and DAM, what should I be looking on those? All I want is to learn some basics so I will know if the etuner is doing something crazy and make me believe is OK. Also, would it make a difference to do the etuner now in the winter vs in the spring or summer? Finally, once the tunning is done if I am going to higher elevation, should I worry about something? Should I get it back to the original map if I will spend a significant time at a higher elevation since the atmospheric pressure changes? Thanks so much for the help.

 

What should I be looking for in the boost?

The calibrator can tell you what you should be looking for with boost.

What is the max boost the car can reach safely (conservatively)? Should I look for sudden boost drops?

There is no one answer to that question. As a calibrator, you're making adjustments to boost, ignition, fuel, and cam timing to make power. What's "safe" for one car is not "safe" for another when only looking at boost alone.

How about the feedback knock, fine knock and DAM, what should I be looking on those?

In an ideal world, you never see a value different than 0 for either knock parameter, and 1 for DAM. That said, you have an active knock control system, so you will get some knock here and there. You basically don't want repeatable knock in a particular RPM/Load, as that's typically a sign that you're running too much advance in that cell. You never want DAM to go below 1, because that means you're pulling timing globally.

That's what the compensation tables are for. A good calibrator will have a general idea what values should be there. You might need a touch-up as the seasons change (every car is different), but you'd only know that with datalogging.
