I want to run 10psi daily and 15psi at the track but dont want to get 440 injectors because of the crapy idle. I have a sfmu and dont want a safc. How much do injectors affect gas mileage? And what size injectors would be the best for my car to run 10-15psi and have good idle?

EX----SQUUUUEZE ME!?

You can have a perfectly SMOOTH idle with 440's and NO SAFC!

Turn your idle FP down to about 14-18psi and your fine. Anything over 22psi, your going to need an SAFC to find tune it.

Just ask SIKE, He does it, as did before I got my SAFC!

its true, my 440s idle fine and they are the cheap bosch ones. i run 14psi daily with sfmu.

I run 14-15 psi daily and i never have an idle issue. My car idles great and since i dont boost all the time i get great gas mileage. If you have a heavy foot and like to boost then your gas will suck, but other than that, the 440 injectors will be good for boost and gas.

I have heard with 440's that idle is a little ruff. But if it idles fine for you guys I guess Ill go with those. Are Bosch injectors good or should I just go for some RC's?

Bosch's arent bad, but RC's will deff last longer.
I had Bosch's to start out with and replaced them with RC's because one of the flow patterns was fucked up on the Bosch.

Arent you guys running pretty rich though? Would 370's be fine for 15psi? I dont want to get a safc and dont wont to be blowing smoke out my exhaust because of how rich im running with 440's.

Here is all the info you need on which injectors to go with!
