adjustable fuel pressure regulator needed?
 

I am going to be replacing my fuel pressure regulator on my 96 z28 and I was wondering about a adjustable fuel pressure regulator there about a $100 more that stock replacement but my car isn’t stock and thinking the adjustable would be better but at what point do you need an adjustable fuel pressure regulator?

Here is the list of stuff done to my car
36lb fuel injectors
Comp cam 280 XFI cam #07-467-8
BBK 58mm throttle body
Heads are shaved .010 ported and polished
pcmforless.com tune
Edelbrock LT1 air gap intake
walbro fuel pump
Plus more tho I don’t think the rest matters

if your tune is for a certain pressure and the stock fpr will not hold that pressure then its nice to have.
