2 schools of thought. You need to test to see what your car likes.

Some say keep the highest vacuum reading by pretending an egg between your foot and accelerator.

Others say vacuum equals pumping losses so you need to WOT it and short shift til desired speed, then maintain the highest vacuum.

Of course afr and timing effect vacuum.
