Tuning injectors

I'm trying to tune my 42 pound Lucas injectors, using offset vs KPa vs volts. What info do I need to do this.

Good luck.

What vehicle?

You need injector flow rate data. Usually good quality injectors will come with a datasheet defining what they flow at different base pressures

roger that

Did you ever find the Flow information for these injectors? Still looking for the Offset information for the Lucas INjectors 42.5#
