Fuel Pressure

What should I set my Feul pressure at? 347, 24lb injectors, walbro 255?

you'll just have to read your plugs for now until you get a tune. also when driving if you notice it breaking up under load then you might want to increase pressure. according to my haynes manual baseline with vacuum attached is 30 to 45 psi. vacuum line detached is 40 to 50 psi.

factory setting is 39 PSI w/ the vac line un plugged. That is what you should set it at.

38-40 psi should be good.

Yep. That's your baseline, then you can adjust up when you get the car tuned if necessary.
