1.Which VE column is used at 105kpa (boost VE or Main VE). Is it best to just keep the two columns 100% synchronized.

2.What happens when PE is enabled and EQ vs RPM table has a richer ratio than PE.vs RPM Does it always use the richer ratio or does PE override if it is enabled?

1. - Boost VE is used from 105kPa+. normal VE is from 100 - 105kPa.

2 - The richest should win.

Cool, so at 104 kpa you are 100% on the Main VE and at 106 kpa you are 100% on the boost VE (with interpolation always taking place within each one).

Nearly correct, the PCM interpolates to the right of the cell it is in.
So it does not interpolate between the std and boost VE table because they are actually two seperate tables.
If you have say '2' in the std VE table at 105kPa and '3' at 105kPa in the boost table then it will literally jump from 2 to 3. So it is probably best to have the 105kPa values from the std VE table as the same numbers (or close) in the boost VE table (as per the doc suggestion).
