Sounds like your old regulator was icing up and lowering delivery. This shouldn't be a problem with the new reg. but if it is make the orifice smaller. With a 1/4" orifice there is a significant pressure drop across the regulator which can cause icing. A smaller orifice will keep the differential smaller so there is less chance of icing.
And yes, either increase the gas a little or decrease the air a little. When you have a neutral flame it will be hotter.
What you describe though is scaling outside the forge which is a natural outcome of bringing hot steel into the open air. A layer of borax will stop the scaling till you've beaten it off the piece. You'll still end up with less scaling and more holes burned in your clothes and hide from molten borax splatter.
Molten borax splatter . . . Mmmmmmm.
