injectors again

Replaced injectors and installed a fuel regulator on my 91.The injectors are ford 24#.Does anybody know the formula to adjust pressure to match stock # 's ,or should I just go with the original of 39#'s
Thanks for any info.

You will probably have to set it lower than stock pressure. You may also find yourself running rich during open loop. Hopefully the reduced pressure will lighten the richness.

Your stock injectors were rated at 22lb/hr. The rumor is that the Ford Racing injectors are 24s but rated at 37 psi of rail pressure. Having said that then you should set your regulator at 37 PSI of static pressure meaning with the vacuum line off. The best way is to get your prom programmed for the larger injectors.
