Is vacuum advance needed with MSD box with a daily driver?

Hey, 273, late comer to this thread and the basic answer is yes, it is a good idea and helps well with mileage.

For a street car, a true driver, a car you want to enjoy and not drain the pockets of money, it's a good bet to use it.

It is well documented and I do t care what anyone else says to the contrary.
The car will run with out it but better with it.
