First off, why are you using Rx-7 injectors?
At factory boost levels (7-12psi) the factory 3sgte injectors are more than adequate.
The OEM fueling system in itself is good for approximately 300hp with supporting mods.

As to the SAFC-II, ditch it.
Plain and simple it isn't going to get you what you are after.

Using the SAFC to lean out your fuel maps has (on the 3sgte in particular)
the detrimental side effect of simultaneously adjusting timing.
Without a proper tune, you run the risk of running too lean.
This will raise egts and the factory ecu will try to pull timing.
This will result in even higher egts.
Leading to blown ringlands and/or blown hg.

If you do not have or are unwilling to use a professional tuner to make this device work,
remove it.

If you are dead set on using it, proceed at your own risk.
Now you know what is at stake.
