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

Thanks guys that's what I thought you can run without but your leaving some mileage on the table. It just seemed every distributor that was to work exclusively with a CDI box had no vacuum advance I started to think that I was missing something.

But I decided to bite the bullet and got a Holley sniper efi with the MSD trigger distributor and no CDI. Comes Friday
