i have both installed
vpc has a 440 stock chip
now i believe that the vpc now puts out a karmen signal
so the setting on the safc should be karmen in and flapper out
both the vpc and safc are zerod out
my car kinda of idles with the safc set at pressure in presure out but i don't thik that this is right
also i am na-t 91 no egr, no csi, 12volt fuel pump mod, i have an afpr, but running stock one right now. with afpr car runs way too rich. it actually runs better when the guage reads zero pressure, then set at 35 psi.
