I found something several years ago that seems to work pretty well. The tighter the transfer tunnels, the lower the opening point needs to be.
For instance, on a two port engine, I might use 118, and have went as high as 114. On a quad port engine like the 390XP though, I will probably use 122 as a starting point.
