how much fuel pressure?

[fiveSFE]

i have a 1g dsm with small 16g, 550cc injectors, walbro 255lph fuel pump, intake, 3 inch exhuast turbonetics wastegate, wit 2.5 inch dump tube. i just got a boost controller, and im pushing 17-18 psi, i set the fpr to about 52psi, i think ti should be higher, my friend thinks it should be lower. What should i set it at? i also have no ems yet

Your friend was right, 38psi without vacuum hose hooked up for 1G turbo.

Why would you think you want 52psi or more? Are you trying to tell us you don't have any form of injector compensation?
