You're assuming the ignition is being blown out by boost. Should be easy to wire something stronger in to see if it makes a difference. 100% sure there are no intake/exhaust leaks?

You don't have enough timing at 100 kpa. It maxes out at 20.25*. A bit of searching indicates a stock 3.2L (albeit without a turbine creating back pressure) should have more like 28*.

What's the recommended timing with 10 PSI?

Do you have a log of fuel pressure and commanded parameters, especially ignition timing? Often there are modifiers that can change the values in the map so they don't tell the whole story.
