I have an AEM 30-0334 gauge/controller and I just ran the wires to connect it to my MPVI Pro. It?s reading the voltage and I?m able to get AFR but it won?t match the gauge, it?s off by about 5 points. I called AEM and got their formula for it and it was closer but didn?t work. I tried both AEM folders in the channel and they didn?t work either. Has anyone else had that problem?
