[QUOTE="bigs10blazer, post: 635555, member: 7054"] We have a MSD rev box part number 6425, the problem is the engine will only rev to 4000 RPMs, if you unplug the rev box for a minute and then started up and throw it in gear it will hit seven grand three, four, five times in a row and then it will go back to 4000 RPM rev limit it is the box bad Or can it be fixed? Or is something else going on ? [/QUOTE]
