evo16g 550 or 660 / safc adjustments?

[section8]

OK, pretty newbie question, but want to make sure I get the right size injectors. I've got the EvoIII16g with supporting mods minus injectors/safc. Question- I have heard you want to run 660's with an Evo16g BUT also heard those injectors are hard to tune with a SAFC. I plan on getting a fmic and running 19-20 psi on pump gas. Anyone have any suggestions on which size I should get? I've read mixed reviews on both types, but only want to purchase injectors once and don't want to upgrade them in the future BUT I want something I can actually tune with an SAFC. If it helps, I have the walboro 190 pump, no FPR, 95 gst, stock mas. Thanks in advance.

Get some 660's.

I had the exact same setup and was at about -34 on the S-AFC so there's still lots of room.

yea i just bought the exact same stuff. ive been told at least 660's everytime. my buddy has a vr-4 with our setup and had real troubles with maxin out the 550's. go with the 680cc precision's, that way you have room to improve!...good luck i cant wait to have my evo on!
