Hey guys. I am looking for fuel upgrades now. Looking for SAFC (1 or 2), injectors (something like 650's, 660's, 680's), fuel pump (walbro 190 lph), wideband or chip.
My suggestion. SAFC II, 660s, 255lph fuel pump (not the high pressure so you dont need a FPR) and a wideband
The fact that the 255 is a standard pump or a high pressure has nothing to do with the fact that you will still need a regulator, it is all about volume, not pressure. With a 255 you will always need a regulator. And when running 650's you on'y need a 190 because those injectors are not big enough to outflow that pump.
