200+ for an extra 10whp AT MOST. Not very cost effective in my opinion. I put 3 SAFC's on 3 diffrent stock cars (LT1 vet, B16 SI, and AE86) and the biggest gain was 10whp, we made 6whp diff on the 4age.
And no the SAFC dosent make the maf read more accuratley, a vein maf runs off of a varible resistior, this means it sends a signal to the ECU telling it how much air is coming into the engine, it dose this by the flap, the flap is connected to a varible resistior that reads voltage and sends that signal to the ecu to tell it how much fuel to give. The safc interupts that signal and tells it what you set it to. in no way dose this effect the accuacy.
