Has anyone ever had an issue with his box. At first, I replaced pretty much everything ignition related to get rid of the misfire after 4000 and under load. I finally swapped back in my old box (6al-2) and the problem disappeared immediately without changing any of the wiring with the exception of the wire to retard the timing when the nitrous is activiated. Just wondering if there is something that could be causing interference with the box causing the issue and maybe other things that could cause it.
