injectors and fuel pressure

[yoyo28]

hi
i have a c20LEt with a ratio of 8.2:0
thinks about 400 BHP at 1.8 bar
I have the 525 CC MSD injectors !
How many fuel pressure must have with this injectors ? ( i have phase 3 EDS for the moment i go to eds this morning for settings it with high tech)
thanks

i 'm thinking i was too rich

Thanks samy

you have to setup the fuel tables in the ecu it will run too rich in areas where you dont have much hp. but if you want to support 400hp you need 4bar pressure and ~90-95% injection timing. but in other rpm areas you need a much lower timing otherwise it runs to rich.
