Well I got my car dynoed and lost power. But hopefully it's just beacause i'm running to rich. Just added 24lb. injectors. My question is would a Apex SAFC or a Mafterburner easily fix this? My air/fuel ratio was right below 15 until 4,000 rpms and went down to 12.2 at 4,500 and stayed like that until 7,000.

Since you changed you injectors, you definitely need a MAFS recalibration. Not sure if the items you mention will help since I have a Pro-M MAFS and just send it back to be recalibrated. From what you posted your problem is being too lean on the bottom end rather than too rich. 12.2 is fairly normal for a NA Focus at the top end. Your F/A ratio should be a smooth curve something like 15:1 at 3000, 14:1 at 4000, 13:1 at 5000, 12:1 at 6000.
