5SFTE Rich as hell....., only when its cold Options

guys just wondering if theres anything i can do to regulate my a/f mixture when the car is still cold. im getting readings of 10-10.5 a/f ratio when its cold. its like this until it warms up. when nits nice and warm, my ratios are good, 14.7 at idle.

i know when the car is cold it takes the reading from the o2 sensor to manage the fuel and when its warm it uses the map sensor.
so is there a way to trick the car into always using the map readings instead????

im using 460 injectors, stock fpr, and SAFC2

thanks!

why dont you just remove more fuel from the low throttle map using the safc?

he only sees the issue while cold, once the engine warms up the AFR is fine, so if he removes fuel at idle it will lean out the mixure once warm.
