Awesome! Glad you got her running good. I personally would leave it on ported vacuum. I tried switching mine to manifold vacuum, and while it idled and transitioned to off idle better, I lost a great deal of my engine braking. I really noticed it trying to stop on a downhill interstate highway off ramp. Enough so that I pulled into the next parking lot I passed and switched it back.
It's easy enough to try out. After the throttle plates are open a bit both vacuum signals are the same. You're only going to notice the difference at closed to near closed throttle. Other people may have different experiences, but that's mine.
