Default Misfires up the wazoo

I just installed some 785cc injectors, and I am pulling misfire codes from all 4 cylinders. I am running a UTEC, the latest version with the fuel map scaled for the 785's. A wide band is on the way, but is it possible that I am still running way too rich? or does it have something to do with the ignition system. Any suggestions for possible solutions? Thanks.

to rid yourself of the misfires, before starting your car, put it to the "ON" position. wait about 5 seconds, then turn on.

remember, the CELs will only go away after about 3-5 starts after no misfires detected, so it might not seem to work at first.

also- probably want to check into getting new plugs. those might be fouled.

<- uses UR 785cc injectors, with one step colder plugs, with the "5 second rule", and has no misfires anymore.

the "5 second rule" worked for my random misfires as well, but i'm running modded stock injectors.
