Has anyone heard of putting a APEXI AFC on their GN? I've talked to some of my import buddies, according to them, all you need is a Mass Air sensor an O2 sensor and a computer and the rest is up to you. This thing has everything you'd need to tune your car. You can even save three separate settings depending on what gas you're using. I was wondering if anyone has used this, or knows if it will work on a 87 GN for sure?
