Ok, I'm stepping in right now before this gets out of hand.

Sleeper, timing maps, like fuel maps, are somewhat different for every combination of engine, gasoline, turbo system, etc... My timing map, for instance, is more conservative than Tim's, yet it would probably destroy your engine.

A good starting point would be for you to copy the timing map out of whichever DIYAutoTune MSPNP map corresponds to your model year. It will not be optimum from a power standpoint, but it should be safe. Keep a sharp ear out for detonation, and take it slow. Once you've satisfied yourself that it's working as a baseline, and after your VE table is properly set up, you can start experimenting with advancing the ignition a degree or two at a time. Ideally, spark timing should be done on a steady-state dyno one cell at a time, but if you're careful and patient you can get it close-ish on the street.
