Does anyone on here ever use an Apexi Super AFC II? I had this on my last car and it modifies the MAF signal. Was curious, once I find all the wires I'm off to the dyno to see what I gain. I have a link here

By modifying the signal voltage all you’re doing is tricking the ECU; sounds dangerous

 

Not dangerous at all, I've had this one and the o.g. AFC on my cars since 2000. I have had no problems at all. The one benefit from it is that the more and more upgrades that you do you can go back to the dyno (unlike custom burned computers, good only for what it is tuned for).
