i have a 450's and uberdata as my fuel management and it is tuned for 10 psi. I have a dc sports fuel rail and a fuel pressure regulator and i am wondering if i turnt he fuel up will i be able to run more boost? I just got it laying around and wondering if it would be useful?

 

dont even bother. sell that crap and buy bigger injectors and then re-tune for more psi/bigger injectors. .

no seriously, raising the base fuel pressure is extremely crude when you have uberdata. i dont know how much more boost you are planning on running(do u have a 3 bar?), but i think you might be getting close to maxxing out those 450's when you get to around 15 pounds. check the duty cycle plots to double check.
