You need to use the safc. Why would you want to zero it out with larger than stock injectors?

i zero it out cause i was gonna tune it to my new set up so i was starting at zero but even at zero my car was rich at idle and even when i went into the negative on the s-afc i wasnt getting the a/f any higher than 12.7 at idle and it was so rich i couldnt even sit in the car

So rich you couldn't sit in the car? If your SMELLING fuel that bad you might be about to catch fire.

You need to go around -18 to -20% as a starting point.
