SAFCII enough for 255 fuel pump

[da kang3]

are my assumptions and what others have told me correct? i/we are under the asssumption that my safcII will be enough to control my 255 fuel pump and i wont need to buy a fuel pressure regulator. i currently and swapping my 7 bolt out for a 6 bolt, and have upgraded the turbo to a clipped b16g, have stock smic, will prob upgrade injectors to 550's pretty soon (still unsure if i need them or not, someone please steer me in the right direction on this), have a 2g exhaust mani, rebuilt head (not sure exactly all the parts but will find out and put them in my profile), apexi full 3" turbo back exhaust, and i believe that's all for now.

and also, is a boost controller, hallman evo dual stage manual boost controller enough for me to get by with for a while, and i do mean a while, on as far as controlling my boost and not blowin my new motor, or do i need more gauges, equipment aor what not? thank you to anyone who is able to help me

the s-afc doesnt control your pump.it controls how much fuel the injectors shoot.you will need an afpr to keep from over-running your stock fpr.and get a datalogger before you start tinkering with your fuel,or you will blow that new engine.youll need 550 or 660 injectors if you plan on going past 15-16 psi on that big 16g.

where is a good place to get an afpr?

Look at the top of your page under "Part Catalog"

I personally prefer the full throttle or charged air bolt-on fpr as you do not have to upgrade any of the fuel lines so it comes out to be alot cheaper. You could also go with the aeromotive unit, but that requires some extra stuff. Take a look in the parts catalog on this site and you can get some ideas. As stated above the afc has nothing to do with the fuel pump. What they failed to mention though is the reasoning. The 255 will indeed over run your stock fpr, which will make your injectors spray more fuel than they are supposed to. This can cause a rich condition. When you are tuning for this you will not be seeing any knock and you will lean it out some more. Next run the fuel pressure is say 1 psi lower, now the injectors are not flowing as much causing a lean condition and making your car knock and pull timing. You see this and add fuel back and run again and see it does the same. You will end up chasing your tail tuning or else end up running way rich and not be making good power. As the poster above said, make sure and invest in a pocketlogger before you start messing with fuel at all and make sure not to go over 680's with that afc.

Not all cars are overran by the 255, www.fuelinjectorclinic.com

most popular are the aeromotives, and make sure it has 1:1
