Adjustable fuel pressure regulator? Good idea or no?

Hey guys i have switched my built in regulator 98 Gt fuel lines with a 97 Gt's fuel lines with detachable regulator. So should i upgrade to an adjustable one or not? My mods are in my sig and I was wondering with the nitrous should I get an adjustable one? Which one if so? thanks
 
Yea I would if I was you.I have the aeromotive one.Had the bbk one but the aeromotive was easier to adjust and looked better.You can see what it looks like in my putfile pic of my engine.The regulator is red.
