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
