Maybe Chris has an idea.
Got an idea for the misfire.
Let's increase your Spark Dwell like this:

Then set dwell Multiplier to 1.0 across the board.
The LS2 doesn't have a multiplier vs MAP (that I'm aware of) so you could probably go a little hotter than the above values for your TT setup. It will make the spark a lot hotter for the boost you are making.
