Safc with stock injectors

[Luckybob2485]

I am looking at upgrading to 560cc injectors, and a 255 lph fuel pump, and a fuel pressure regulator. But my car needs to be tuned pretty badly, so i am curious as to if the safc would be able to take out much fuel if i am still on the stock injectors? And then get it retuned with the larger injectors later on. Thanks.

yes the s-afc can lean out your stock 450's

If youre running the stock injectors, your ECU should be doing a good job in the "tuning" department. (unless youre running over stock boost or a bigger turbo.) If the car is just running like crap, check for boost leaks.

I am running a t28 on 16-18 psi, the car also has a greddy front mount and a 3 inch turbo back exhaust. The car is running well, it has quite a bit of power, but its getting pretty poor gas mileage, and if i throw in the safc ill be able to adjust the air fuel ratio and improve on gas mileage and power. I just wasnt sure if there was much i could do with the stock injectors.
