S-AFC or injectors

[mitsugsx95]

Im going to start off by saying that i kno i need both, but which one would i get the most out of with the current mods on my car. The S-AFC to tune the stock fuel pump and injectors or go strait to the injectors. Any info would be helpful ( kind of clueless when it come to air/fuel things).

You need the SAFC to tune for bigger injectors, so get the AFC first. If you get the inj. first, the car won't run right.

What kind of performance can i expect out of the S-AFC w/ just having the stock fuel system and injectors?

Depends on the boost you are running. I generally would get AFC, then fuel pump, then injectors, in that order, with intercooler upgraded somewhere along the way.

Not too much.

When you get the AFC, don't you need some sort of monitoring tools such as an EGT gauge and O2 voltage readout, as well as some kind of logging device, in order to keep tabs on what you're doing? The "blue wire mod" enables O2 readings with the AFC, is that right?

yes, without some type of logger or atleast an EGT gauge the AFC is going to do you no good. You will be able to change your fuel trims but if you cant monitor what its actually doing whats the point?

save up and et them at the same time. In the mean time buy an egt gauge or a logger so you'll be able to monitor what's going on when you do get the injectors and afc.
