I have some fuel coming out of the vacuum port on my reg. Is this normal or do I have a leaker?

You've got a leaker, there shouldn't be anything coming from that hole.

Replace the regulator, it should not leak.

The adjustable fuel regulator was run and what happened? Is this something that all of the big strokers will need to run? Will it change the mapping in any way? Which one are you running? What is the stock number and Manufacturer? Etc. etc

Thanks

It was run.On one quad it did help richen up the mixture but only up to 60 or so psi.After that cranking up pressure didnt seem to matter.Thinking was injectors were flowing max.The other quad the pressure fell off by almost 10lbs at high rpm.So either regulator or pump werent working.Right now I would say no dont get a regulator didnt make a big enough difference to matter.More gains were made in flow with just mapping.We want to get the fuel injectors sized right which is really the right,safe way to do it.
