Holley Blue will work fine and you can't beat a Holley 12-803 regulator. I think Jegs sells them in a combo for about $130.00 or so.

Those rergulators are cheap but they work great. Look at what all the outlaw guys and Promod guys are using.

Invest in a good flow tool. Stay away from liquid filled guages.

FP can be anywhere from 4.5 to 12

I run mine at around 5-6 depending on the weather and how the plugs look.

i used to run the holly black with thet regulator.
the pump was good but i found the regulator to flutter under running conditions.
i would flow it and it would be mint, i was having sputter issues and i put a gauge in the car hooked to that reg and it would flutter say i set it to 9psi it would go from 7 to10.
so i went to an aromotive and was good to go.
since then i put a magnafuel in and it runs my hole car.
i have an aromotive regulator for high pressure then from there off one port it goes to a kick down regulator and to my fuel noid.
i run more in the 7-9 psi range depending on weather. but again 2 different cars. depends what nitrous set up your running
i just bought a nice n2o flow gauge from dave. just be sure you flow it with the same size fuel jet as your running in your kit,

so you run a low pressure regulator for n20 after a high pressure regulator for your fuel? or do your run a carburated intake?
i have always been under the impression you want to T off the fuel source before the regulator...
