24 LBS injectors on 94 GT

I have a basicly stock 94 GT Vert with the mods below. Would it do any good to put 24 LBS injectors one it? I have a adjustable fuel regulator.

Thanks, Jason

Absolutely not.....and why would you have your fuel pressure that high??You're boggin the motor,back it down to @32-35psi,and leave it alone until you do more mods that warrant more fuel.

Stock fuel pressure is 39, Would it be better to set it below 39?

Stock fp with a non adj fpr,is typically 30-33psi at idle with vac,and will jump to 42psi or so,under load.If you were seeing that much on a stock reg,then the reg was sloppy.If you trim it out to where I suggested,you will get better gas milage,along with smoother acceleration,and most likely,...a little more power.At 85k miles,your injectors have seen better days,and tend to become sloppy,and puddle with stactic pressures above 48psi.Your present combo doesn't warrant the need for extra fuel at this time,so why waste it?

Hook the vac line back up,and that will be good.It should be close enough if that was originally set without vacumm.....that should bring your idle pressure to @ 33psi or so with vac.
