I have been running MHD Stg 2+ but wanted to try JB4. I just finished installing my JB4 with MHD BEF. When I started the car it ran really loud for a few seconds then tapered off to normal idle. About 15-20 seconds after it started idling normal, the engine cut out and my JB4 started buzzing pretty loudly. I disconnected the battery as soon as possible but have no idea what to do now. I then disconnected the JB4 box only and the car starts so it is something to do with the JB4. When I plugged it back in and tried again it started and puttered out in about 3 seconds. I've searched but I can't find anyone having the same issues. Any help is greatly appreciated.
