My guess is since we are talking about an APEX SAFC, they are talking about adjusting the correction factor by -10% or -5%.
Neither or which I would do unless i was able to monitor with a Wideband in real time.

The easy way is to get a Zeitronix wideband unit. It has a function built in called narrowband switching point. Basically, it will feed your stock ecu a slightly skewed O2 signal which will allow you to still use the stock ecu and run richer or leaner. What it does is tell the ecu is 14.7 when in reality the engine is running at 15.5 or so. This will allow you to save fuel during idle and cruise. Under full throttle, the engine reads off the MAF sensor and internal fuel map without referencing the O2 sensor. That is called open loop operation. So in theory using the Zeitronix wideband you can run a tick leaner at idle/cruise and still retain proper fuel at full throttle.
My friend is doing that on his IS300 and he's getting a notable fuel savings every tank.
