I do have a Aem fic and the map sensor is stock ro not read pressure I assume. I'm guessing the black box is some sort of clamp to trick the stock ecu to not see boost. I am assuming there is an issue with the map sensor bc at part throttle at cruise the AFR is all over the place so I figured I'd start with the map sensor. Also when I jamb on the throttle is takes a few seconds to smooth out. Almost like a hiccup
