Maybe I should rephrase the question.
I have a base tune and I am looking to increase timing. How do I know when I have increased it too much?
It will get noisey and possibly excessive smoke. Timing is relative to the rpm and pulse at that moment. Have you ran what you have through the calculator to see where you are at with timing now?

No there isn't really much instruction. It will take you a enormous amount of time to learn the dos and don't s. Take it slow with small adjustments on one item at a time to find the correlations between various components of the tune. There are many limiters within the tune as well. Learn how they work and what they do first.
No there isn't. You will hear the timing/injector rattle very distinctly. If you run the tune through the program calculator you can see where stock items fall. There is tremendous range in the stock tune. A performance tune won't resemble that.
If your using stock pulse and you begin to add timing, smoke will be a byproduct of too much timing. Remember that pilot timing is based off of main timing. So as you increase main, pilot also increases.
As for top end fueling timing, with a re-entrant piston, 50% BTDC is ok with stock pulse...start going over stock pulse, you'll need to advance your split.
If you have access to a load cell dyno..that would be your best friend.
With diesels, no knock sensors, so you have 3-potential ways to find max timing...
1. Dyno
2. Track
3. Calculated timing
