I wont pretend like im really well versed on how the venom and SAFC work to modify your A/F ratio but I was under the impression they intercept a signal coming from one of the sensors, be it MAP, MAF, or O2, and then modifies it and sends it back to the PCM thus making the PCM think it needs to richen up the A/F in the case of the Venom Kit, and Richen/Lean in the case of the S-AFC. Now if this is indeed how they work, I would think they would interfere with each other.

I would rather you be right tho because just buying the SAFC and tuning exclusivly with that would be a lot easier on us, if it works.
