Talking Re: Upgrade pump options
By routing the boost 20PSIG to the Fuel Presure Regulator I was running about 10:1 or WAY rich. THe injectors have much more capacity if the pressure differential across them is held at a modest 60 psig.

I was going to 80 psig on the fuel rail and see that that has to be tailored to more like 65 to 70 psig with my data logger doing the open loop correction of the F/A to dynamicaly tune the fuel pressure , giving the f/a numbers that I want to get.

I just installed the fuel pressure sensor on the rail so I can log it also. Woody Enjoy.........
