I would get the hallman RX pro, if you get the soft spring it wont boost higher then 14ish.

Me and another guy I know both have it and love it. Boost holds at a constant 21psi all the way to 7k, and barely tapers to 19-20 past that.

Hope this isn't an idiotic question!

I have a Turbosmart Boost Tee MBC. Boost holds 21psi till 5500rpm then tapers to 18-19 by redline. I am using the BOV line as the boost source instead of the turbo nipple. May I ask how yours is set up?
