CFs are correction factors. The is the correction the ECU applies to the requested timing to avoid knock/pre detonation. In short, if your timing is advanced a lot using a revo sps switch, the ECU might be pulling back the timing to avoid pre-det, which would make the car feel hesitant.
Your best bet in my opinion, is to borrow an SPS3 switch off someone, reset the boost and timing settings and see how she feels after.
